Re: [ubuntu-studio-users] weird ssh issue

[bart deruyter]

Hey all,

thanks for the reply Ross. I managed to solve it, though I still don't know
what the issue was. There was one thing I had not rebooted yet, the router.
Once I did that, it worked again.
I'm really sure I didn't enter the wrong ip-address because after I
rebooted the router I used the history of commands in the terminal and now
it did work, so it should have earlier too.

My guess is an IP conflict must have occurred because of a glitch in the
router.

Thanks,
Bart

[ubuntu-studio-users] weird ssh issue

[bart deruyter]

Hello,

I've got a weird issue here. I'd like to move some of my finished videos to
a drive connected on a raspberry pi 3 device, which is running LibreElec.
I recently upgraded to 20.10, on my laptop, fresh install actually, with
the new KDE environment, and since then I can't reach this device over ssh.
I get this as result: ssh:
connect to host 192.168.1.xx port 22: No route to host
(last number is a real number, don't worry :-) )
username is correct, I don't even get the chance to enter a password.

When trying:
nmap -sn 192.168.1.0/24, the ip-address of the device is not listed.

The strange thing is, when I ssh to the same device with my android phone,
using Termux I do gain access without any issues at all. Checking on the
device, it should be there, the IP has not changed, checking the connected
ip-addresses on the router, it is listed too.

Even stranger is, I have another raspberry device I can connect to over ssh
with my laptop.

The only thing I can guess at the moment that might be causing it, is the
last number in the ip-address. It is quite high, maybe that has something
to do with it. The other raspberry device runs raspbian and has a much
lower ip-address. Is there some limit built-in some config file which
prevents scanning the ip-addresses from a specific number onwards for some
security reason I'm not aware of?

thanks in advance,
Bart

Re: [ubuntu-studio-users] no HDMI output

[bart deruyter]

Hi all,

I managed to fix it :-D

The issue was secure boot. So when having secure boot on while installing
the proprietary nvidia drivers, the HDMI port on the laptop does not work.

The nvidia drivers even aren't loaded, though they show as 'installed' by
the GUI installer of proprietary drivers.

If anyone has this issue in the future:

purge all nvidia drivers, reboot to BIOS, disable secure boot, reinstall
drivers... et voila, it works :-)

Sidenote: the display manager should be lightdm, I think. I've read
numerous reports gdm3 causes issues with hdmi too, but I use lightdm
anyway, so I didn't test it.

thanks for offering your help Ralf :-)

grtz,
Bart

[ubuntu-studio-users] no HDMI output

[bart deruyter]

Hi all,

I've got a problem that starts to become a real issue. I need my HDMI port
to get working for a video projection.

It didn't work in 18.04, now upgraded to 19.04 and it still does not work.

specs:
HP pavilion, nvidia, GP107M, GeForce GTX 1050Mobile
now runing ubuntustudio 19.04.
driver in use: 418
xrandr says: HDMI-1 disconnected (normal left inverted right x axis y axis)
xrandr --listproviders shows:
Providers: number : 1
Provider 0: id: 0x44 cap: 0x9, Source Output, Sink Offload crtcs: 3
outputs: 2 associated providers: 0 name:modesetting
nvidia-settings is set to performance, and in nvidia-kms.conf I commented:
nvidia-drm modeset 0
as suggested in several possible solutions.

I hope someone here knows a possible fix, or solution...

thanks in advance,
Bart

[ubuntu-studio-users] apps in sudo - fonts turn to squares

[bart deruyter]

Hello,

since yesterday applications  requiring sudo (e.g. synaptic) have trouble
with loading fonts. When launching synaptic it starts out fine, I can read
everything, but when I perform a search for some software, the fonts are
replaced by empty boxes, as if the fonts aren't found anymore. So it
becomes impossible to use.

As a test I launched nautilus as sudo, and the same thing happened. First
it was OK, but when I performed a search, the fonts got replaced too while
the search continued, then gradually the fonts came back. In synaptic they
don't.

I've already tried sudo fc-cache -fv hoping it was a caching problem, but
it doesn't help.

Any idea's?

grts,
Bart

Re: [ubuntu-studio-users] writing a CD-image from a wav and a cue file

[bart deruyter]

They asked for songs as seperate wav's or an image file, I now sent them
both, also the image file because the songs are seamlessly woven against
each other. I've seen it happen that there were gaps added, when the
seperate songs were used.

Now waiting for delivery :-)

Re: [ubuntu-studio-users] writing a CD-image from a wav and a cue file

[bart deruyter]

I managed to get it done with a workaround, it's not an iso though, but
from my research it seems that it is not really possible, or good to make
an iso from an audio CD because an audio CD doesn't contain data blocks...
a bit too technical for me.

Anyhow, I managed to create a .bin image, which is aparently meant for
audio-CD's, together with a toc by using good old 'Rhythmbox' :-) .

I did have to create a physical CD first though, and in my eyes that is
redundancy, it should be somehow possible to create a bin-file without
having to burn an actual CD.
(I think it used to be possible in previous versions of Ardour, if I
remember it correctly, but now it isn't anymore)
Then in Rhythmbox, copy CD to image, which creates a bin-file.

 When trying the same in K3b, copying the actual physical CD to an image,
K3b again created a series of wav files instead of an image file :-( .

Anyhow, Rhythmbox saved me, I now am sending our album to get pressed..
exciting :-D .

By the way, the artwork and the music, it was all written, recorded and
mixed in ubuntustudio with the extra packages of KX-studio ;-)

[ubuntu-studio-users] writing a CD-image from a wav and a cue file

[bart deruyter]

Hello,

I have now spent a few hours on finding a way to write an audio-cd image.
Time to ask for help :-) .

Here some background to understand what I need to achieve:

I've got all the songs of my album in one long ardour session, which I
exported as one long wav-file, together with a .cue file.

>From that wav and cue file I can perfectly write regular physical
audio-CD's with K3b, (brasero seems to fail with cue files completely) but
when set K3b to 'only create image', it creates 13 seperate wav files,
which are the 13 seperate songs. I'd expect a .iso, but whatever I try, I
only get those 13 seperate wavs.

So, I guess I must be missing something fundamental here.. but what?

In ohter words, is there some way to create an iso from only a wav and a
cue file? I need it to send it to the company who'll press our CD's.

grtz, and thanks in advance
Bart

[ubuntu-studio-users] midi lag with roland F20 piano, usb connected

[bart deruyter]

Hi all,

I'm having quite a midi problem here. My digital piano, Roland F-20 is
connected to my PC by usb. At first it seems to work quite well, but out of
the blue, while working in Ardour (5.11.4) , when editing notes, I don't
get any sound anymore. Then I notice the notes get played anyway, with a
really giant lag,

I'm not talking milliseconds, I'm talking seconds to even half a minute.
Most of the time playback just stops and then suddenly, as if the system
wants to catch up, all notes are played at such a speed it sounds like the
notes are played simultaneously (maybe it even is simultaneously). It
happens that my piano is unresponsive (I think, no music is played) for
minutes.

I do connect with jack-midi, because Ardour doesn't use alsa midi anymore.

Is there any known issue with usb-midi? Or should I change some setting in
a config file? Perhaps somewhere a change in priority?

My system is Ubuntustudio 17.04, 64 bit.

Grtz,

Bart

Re: [ubuntu-studio-users] audio morphing

[bart deruyter]

Hey,

thanks for the replies. After I sent the email, I thought of pd and csound
too. Recently I discovered Cecilia5 which seems to be using csound.
Unfortunately Cecilia5 in ubuntu's repositories is not working, the one
downloaded from their website does work luckily. I haven't found morphing
yet in the modules, but will check it out a bit more. There is plenty of
granular synthesis going on in it. After some research I also found chuck,
anyone experience with it?

Emulated synths are indeed not good in general, in linux. But there are
some really interesting projects going on, most often using sample based
instruments.

Lacking too is virtual singers which I would let sing lyrics. There are
plenty for other operating systems (all propriatary of course), and of
really good quality. It may sound stupid, many would reply "go get a real
singer" or "sing it yourself", but for choir work for example it is way too
expensive (and I don't have a multiple personality disorder to be a choir
:-) ).
I'm getting into making music for games now so that's another thing I could
use very well if I stick to open source tools.
The same I can say about all virtual equivalents of acoustic instruments in
general. A friend of mine, running windows, Cubase and Kontakt has a
virtual Steinway, connected to it's keyboard, you can even hear the pedals
and the harmonics of the strings.

So far I try to be creative and figure out new and good sounds with what I
have in linux and open source. It works, and it actually makes me more
creative, but it limits myself too. In other words, I often have to sound
'alternative' or 'experimental' also when I don't want it.

I'll look into pd again, I have in the past, but it seemed intimidating. I
am a musician, not a sound engineer and having to dig up and study theory
about how sound is composed in terms of frequencies, phases, amplitude,
synthesis, oscilators and such is of course rewarding when it's about
gaining knowledge but not that productive if I just have to get my music
done. The best thing would of course be a plugin for ardour :-p, but hey,
if it does not exist, I'll try some hacking anyway :-) .

grtz,
Bart

[ubuntu-studio-users] audio morphing

[bart deruyter]

Hi all,

I was wondering is there an open source application for audio morphing? I'm
not talking about mixing two sounds with fades, real morphing. An example
of an application I found on the web is this :
http://www.zynaptiq.com/morph/

I have been to a concert recently, contemporary jazz, where just by the
acoustics I had the impression that the piano was morphing with the vocals.
This got me thinking, what if I could actually morph vocals with violins or
a guitar solo...

[ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

Hi all,

I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and kxstudio
installed through software sources.

My soundcard is an Echo Audiofire 12, connected with firewire.

Since 15.04 when I start jack it works fine as long as I don't run any
other application which requires sound, before starting jack.

it is consistently going wrong when I for example start chrome, exit chrome
and try to start jack, using claudia, or qjackctl, or commandline.
the message qjackctl throws is: JackServer::Open failed with -1

When I log out of the system, then log in again (no reboot required) it
works again, as long as I start jack first.

Also, when I use chrome while running jack things seem to keep working,
though I have ben thrown out of jack too.

- I checked if I was in audio-group, which I am, otherwise it wouldn't work
at all.
- I turned autospawn off for pulseaudio and killed pulseaudio befor
starting jack
- tried out various settings in qjackctl.

None seem to have helped.

How can I trace the source of the problem? If it is a known issue, anyone
idea's on how to fix this?

grtz,

Bart

Re: [ubuntu-studio-users] ubuntu-studio-users Digest, Vol 100, Issue 4

[bart deruyter]

thanks for the ideas, but again, these are not solutions.
let me explain the problem again in real life:

1. I start claudia, run ardour4 for a recording, then I decide to stop
after an hour.

2. I exit ardour, shut down my soundcard (remember: power-consumption)
which kills jack, because it has no soundcard to run anymore, or I first
stop the studio in claudia and then turn off my external soundcard.

3.and I go surfing a bit as a break.

4. Then I want to start again, fire up my external soundcard and I want to
run claudia again to launch my apps, like ardour, guitarix, etc...

5. only to discover jack won't start anymore.

6. Only solution so far: log out and log in again

I hope this explains the problem better. I don't want to have to log out
each time I have done something else  then audio-work for a while. I can't
believe this is a normal thing to happen.

grtz,

Bart

  I'll try using the pid to kill jackdbus, though I thought it was killed
  by right clicking in systemmonitor and clicking on destroy process. That

 As long as jack hasn't crashed, there's no need to kill jackdbus.
 If you'd rather use jackd instead of jackdbus, you can disable dbus
 support in qjackctl settings (that is, if you are using qjackctl to
 start jack in the first place).

I find it weird that it used to work in previous versions of ubuntu and not
now.

I run an external device as soundcard (audiofire12) and don't keep it on
every day (I do mind to keep power consumption low, so I don't activate
things when I don't need them) . Starting up with jackd running is not an
option I'm afraid since my soundcard won't be on, and jack would definately
crash.

Ubuntustudio should be capable of running both internal soundcard and my
audiofire. Using two soundcards is even described as a solution to have
both jack and pulseaudio running, so it should work.

grtz,

Bart

2015-08-13 15:55 GMT+02:00 Edward A Schober t...@schober.us:

 Perhaps you should run claudia on boot?

 Once you decide to use jack, it should be part of the environment -
 always there.

 If you use $HOME/.jackdrc jack will start with your user session.
 if you make a file /etc/jackdrc it will be the default jack session
 parameters for the computer.
 A clean Ubuntu-Studio install does not have these files.  I think
 .jackdrc gets generated when you run qjackctl for the first time.  I
 think claudia reads and writes ~/.jackdrc.

 There is a discussion about jackd vs jackdbus at


 http://jack-audio.10948.n7.nabble.com/more-jack-qjackctl-madness-td8914i20.html

 Which I have not yet figured out.

  Hi all,
 
  I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and
 kxstudio
  installed through software sources.
 
  My soundcard is an Echo Audiofire 12, connected with firewire.
 
  Since 15.04 when I start jack it works fine as long as I don't run any
  other application which requires sound, before starting jack.
 
  it is consistently going wrong when I for example start chrome, exit
 chrome
  and try to start jack, using claudia, or qjackctl, or commandline.
  the message qjackctl throws is: JackServer::Open failed with -1
 
  When I log out of the system, then log in again (no reboot required) it
  works again, as long as I start jack first.
 
  Also, when I use chrome while running jack things seem to keep working,
  though I have ben thrown out of jack too.
 
  - I checked if I was in audio-group, which I am, otherwise it wouldn't
 work
  at all.
  - I turned autospawn off for pulseaudio and killed pulseaudio befor
  starting jack
  - tried out various settings in qjackctl.
 
  None seem to have helped.
 
  How can I trace the source of the problem? If it is a known issue, anyone
  idea's on how to fix this?

Re: [ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

I already had jackdbus disabled in my search for a solution, was one of the
steps I took. And I filed a bug report, describing behavior with
pulseaudio-module-jack, and without it, in case I'm not alone with this
issue. In Ubuntu 14.10 this wasn't an issue either for me and I kept it in
place too. Luckily, using two sound cards, internal for regular audio, and
audiofire12 for real audio work goes just fine :-).

grtz,

Bart

 So, if anyone else might have this problem of jackd not wanting to start
 again after having exited in the same session, and doesn't need it the
 pulse-jack sink: remove pulseaudio-module-jack.


 i typically leave it in place, in case, for some reason, i would need it,
 in the future, but, i just disable the dbus in the qjackctl settings.. dbus
 tickbox in misc settings, iirc...

 as an idea to get jackdbus stopping and then startup again I used as

 sudo kill -9 4327 (the number is the pid of jackdbus)

 ubuntustudio. So it is not gnome related, but a more general configuration

 Hi,

 Replying to digest emails breaks the threading

 you can avoid this by using MIME Digest:

 At least consider to edit the subject, to the subject of the thread you

 The subject ubuntu-studio-users Digest, Vol 100, Issue 4 is not good
 for people shifting through the Internet/list archive and it's also not
 good for those who follow the mailing list, thus also not good for

 Hi all,

 I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and
 kxstudio installed through software sources.

 My soundcard is an Echo Audiofire 12, connected with firewire.

 Since 15.04 when I start jack it works fine as long as I don't run any
 other application which requires sound, before starting jack.

 it is consistently going wrong when I for example start chrome, exit
 chrome and try to start jack, using claudia, or qjackctl, or commandline.
 the message qjackctl throws is: JackServer::Open failed with -1

 When I log out of the system, then log in again (no reboot required) it
 works again, as long as I start jack first.

 Also, when I use chrome while running jack things seem to keep working,
 though I have ben thrown out of jack too.

 - I checked if I was in audio-group, which I am, otherwise it wouldn't
 work at all.
 - I turned autospawn off for pulseaudio and killed pulseaudio befor
 starting jack
 - tried out various settings in qjackctl.

 None seem to have helped.

 How can I trace the source of the problem? If it is a known issue, anyone
 idea's on how to fix this?

 grtz,

 Bart

Re: [ubuntu-studio-users] group button is not running

HI,

what specifically are you asking? What do you want to achieve, or what do
you want to do?

So, group-ungroup button does not work, are you looking for another way to
group? Or another technique? Other software?

 Hi ubuntu studio,

 I think Tupi is the best animation application on linux. But i have a
 problem to use it. The Group-ungroup button is not working. You know i
 have installed the the newest one (tupi_0.2-git04). I am using ubuntu

 Any idea? Thanks.

[bart deruyter]

HI,

I've had this issue as well, quite a while ago. The only solution was to
change to another desktop manager:
sudo dpkg-reconfigure lightdm

(if you have lightdm installed of course.)

and even after switching back:
sudo dpkg-reconfigure kdm

the problem was still solved.

HTH,

Re: [ubuntu-studio-users] tuxguitar broken?

[bart deruyter]

For any other interested people:

Seems like the issue is not caused by any ppa, nor using any version of
java, but by oxygen-gtk as gtk setting in look of KDE. Changing it to
something else, seems to solve the issue, at least here it does:

http://ubuntuforums.org/showthread.php?t=2186523

By the way, I understand that limiting support to ubuntu-studio packages is
limiting scope, but at the same time suggesting to use third-party ppa's as
a solution.. well... it is a contradiction, isn't it?

If support for ubuntu-studio is strictly limited to the softwarepackages of
ubuntu-studio itself, then don't suggest third-party packages as a
solution.
It would mean the person in question would not be able to get any help in a
later issue, because of actions suggested by the provider of the support.

Grtz,

Bart

 Mike,
 - I just sent the error message when starting in terminal in my previous

 - Installing the ppa, and using this version of Java is what I already
 tried too. First attempt was with default Java in Ubuntu, which is 7 . This
 Ubuntustudio 13.10 is installed this weekend KDE is added and KX-studio
 repo's,
 - Just tried openjdk-6 : no fix

 Time for a bug-report?


 no.. no need for a bug report here, since you are not using ubuntustudio.
 you will troubleshoot this with kxstudio support. sorry, i had intended
 before to ask you to use the suggestion from the error message and run the
 command from the terminal with the  ulimit -c unlimited  option.. you can
 try the unsupported ppa i mentioned which will offer java 8 AFAIK.. you can
 try with stock ubuntustudio from a live CD.. good luck!

 what version of java? you could try adding an unsupported ppa to add a
 potentially newer version http://www.ubuntuupdates.org/ppa/webupd8_java

 could be that tuxguitar needs an older version. what does tux guitar
 report requiring? what are the error messages in the terminal if you use
 the terminal to run the application and get it to crash?

Re: [ubuntu-studio-users] firewire broken after upgrade

[bart deruyter]

Hi guys,

I finally managed to get my AF12 working. The issue was the PCI-firewire
card that was broken and even prevented to let the onboard firewire port to
work.

I unplugged the PCI-card and everything started to work :-D

I read here about the firmware too. I won't upgrade the firmware, since I
just got my system working, but in a later stage, when the ffado-drivers
have been updated to that new firmware, is there a way to update the
firmware of my AF12 using linux? I've read it has been done in windows, but
in ubuntustudio, is it possible to do?

Grtz,

Bart

 Hi Mac,


  Any chance of getting a 12.04 package? (this would allow me to quickly
  test on a AF12 with 4.7 firmware)

 I pushed it into my repository. Then confirmed that the build for lucid
 failed so remove lucid package.


  many more lines like above

 Yes.  Retry mechanism and fallback mechanism which I added causes these
 lines. Once these commands are failed, then retry several times. If all
 retries are failed, then fallback to another way.


  The GUI appears but, it won't identify the device, save setting button
 is grayed out,
  clock source  sample rate grayed out, etc.

 My workaround causes this situation. When you see this, inner FFADO,
 retries of the command are executed because the command failed once. So
 please wait a little time. Then it may be active again.

 This is not a perfect solution but my best effort.


 Regards

 Takashi Sakamoto

Re: [ubuntu-studio-users] firewire broken after upgrade

[bart deruyter]

Hi all,

got some news. I tried the audiofire12 on another machine, running
ubuntustudio13.10 live usb stick. Guess what, it worked on the other
computer. I'm releaved it's not the audiofire12 being broken, I can't
afford a new one yet.

Then I tried it with the usb-stick on the machine where I know t doesn't
work with the installed system(s), and it does not work, booted from the
usb stick either.

I'm guessing that the firewire ports on my machine are broken, or that
there is some kind of conflict, which prevents it from working. I suspect
the latter, because I have an onboard firewire port and a PCI card with
extra firewire ports and neither of them work. It would be quite a
coïncidence if both would get broken at the same time.

What could cause this kind of conflict to result in ports to not being seen
by the system? Maybe the fact that I have an onboard firewire port and a
PCI card with more of them?

I'm going to try and see if I can create a bootable windows usb-stick, and
see what happens if I can boot on windows.

grtz,

Bart

 You could be the only one with that device on this list. I read about how
 it worked with one FireWire stack and not the other and decided against it,
 though that was years ago and I hope support is better. Ideally, it would
 be up to echo to provide you support. They may not officially support
 Linux. I would rule out a hardware issue. If the device worked with the
 13.10 live CD and doesn't work now with the 13.10 live CD, then that could
 indicate an issue with the hardware somewhere. I would want to take the
 device to another machine with the same, known supported live CD, and
 ideally test it with whatever operating system echo officially supports.

  Hi guys,
 
  last attempt to find help before I do a fresh install:
 
  I have quite an issue with my audiofire12 (firewiredevice) since I
 upgraded to 13.10. Firewire worked at first, but yesterday morning there
 was 'nothing', no sound, no firewiredevice detected by the system.
 
  I have been busy half a day on trying out different things, nothing
 seems to have worked so far, so now I'll ask it through this mailing list:
 how can I fix it?
 
  For starters, I have the output of ffado-diag added here, if that would
 show interesting things to solve it. I see the new firewire stack is
 present, not loaded on boot, not activated and /dev/raw1394 is not present.
 
  My guess that is the issue, so how do I get this stack loaded on boot,
 active and with /dev/raw1394 node present, if that's necessary, and is it
 the new firewire stack that I have to use in 13.10?

Re: [ubuntu-studio-users] firewire broken after upgrade

[bart deruyter]

Thanks for the info Takashi,

I tried what you suggested:
sudo modprobe firewire_ohci

ffado-diag tells me then the new 1394 is loaded, but not active

sudo modprobe firewire_core
doesn't result in anything

I now connected my video camera, as firewiredevice, to check if it might be
my audiofire12 being broken, but it does not get recognized anymore either.

trying:
ls /dev doesn't show any fw devices after loading the firewire_ohci module.

I'm starting to guess if it would be the firewire ports itself that are not
active for some reason...

Grtz,

Bart

 Hi,

 I'm a developer of FFADO upstream and recently work for improvement of
 AudioFire driver. This year, I spend much hours with Ubuntu Studio and
 low-latency kernel for my developing and have no problems about host
 controller.

  bart

 As a quick grance of your logs, firewire_ohci/firewire_core is not loaded.
 So let's try to modprobe them. Then check if character devices exists
 (/dev/fw*).

 If you can see /dev/fw0 and /dev/fw1, FFADO can driver your AudioFire.

  Mac and Kaj

 I confirmed that FFADO cannot drive AudioFire12 (and maybe AudioFire8)
 with firmware version 5.2.1 or later. Recently I committed my workaround
 for this issue to revision 2451-2453 and need testers. Would you please
 test the recent FFADO? You can get debian package for lucid and saucy from
 my PPA.
 https://launchpad.net/~mocchi/+archive/instruments

 If you need package for other Ubuntu version, please inform me. I'll
 upload it into my PPA.

 seems to have worked so far, so now I'll ask it through this mailing
 list: how can I fix it?

 For starters, I have the output of ffado-diag added here, if that would
 show interesting things to solve it. I see the new firewire stack is
 present, not loaded on boot, not activated and /dev/raw1394 is not
 present.

 My guess that is the issue, so how do I get this stack loaded on boot,
 active and with /dev/raw1394 node present, if that's necessary, and is
 it the new firewire stack that I have to use in 13.10?

 I don't have the same issue with the recent kernel, so it's not the
 kernel.
 The message is puzzling, since you do have the stack. It is there, just
 not active in your case.
 I would suspect a hardware problem. And that could be related to the
 kernel version, that the most recent firewire drivers don't work on your
 hardware.

 You could just download and install an older kernel version and see if
 that makes a difference.
 You can find all the packages for linux-lowlatency here
 https://launchpad.net/ubuntu/+source/linux-lowlatency

 For me, the stack is present and loaded.

 Check with the ffado folks on their mail list if you can find out
 something more.

I installed and tried 3.5.0-17-lowlatency kernel to check if that would

 Hi guys,

 last attempt to find help before I do a fresh install:

 I have quite an issue with my audiofire12 (firewiredevice) since I
 upgraded to 13.10. Firewire worked at first, but yesterday morning there
 was 'nothing', no sound, no firewiredevice detected by the system.

 I have been busy half a day on trying out different things, nothing seems

Re: [ubuntu-studio-users] firewire broken after upgrade

[bart deruyter]

Hi all,

I have made several more attempts, checking the blacklist-firewire file,
the lib/udev/ffado.rules file, rebooting, reïnstalling... nothing seems to
help.
The end of the ffado-diag report does say :

=== REPORT ===
FireWire kernel drivers:

FireWire kernel stack not present. Please compile the kernel with
FireWire support.

loading  the module firewire-ohci by: modprobe firewire-ohci does load the

I'm starting to guess there is something wrong with the comping of the
kernel... it's not a custom compiled kernel, it comes straight out of
synaptic. Maybe there is the core of the issue?

Would a bug-report be appropriate now?

 Hi Bart,

 Can't offer any help. I let the ECHO windows app upgrade one of my 3
 AF12's to 5.8 firmware, now it doesn't work with UbuntuStudio12.04.

 I'm waiting until I get some time to build an experiment system so I can
 build the svn version of ffado to see if that fixes the firmware rev issue.

 I need to figure out how to get the rev of the two that still work...and
 find the firmware files. I've seen none of them around, so I either need to
 get 5.8 to work or I'll have one that works with windoz and 2 that work
 with UBS 12.04. :(

 I know I won't be able to look at it until late Nov.

Re: [ubuntu-studio-users] Need a CLI command to recursively copy my home folder.

[bart deruyter]

Alex,

I've had a similar issue, a while back, couldn't log in a Desktop
Environment anymore. It looped back to the login screen. Is it familiar?
The solution was installing gdm from command line, sudo apt-get install
gdm (running kde here, which uses lightdm) and then sudo dpkg-reconfigure
gdm.

Now I have upgraded to 13.10 too, but gdm seemed to be broken, only a black
screen showed up. So then I had to sudo dpkg-reconfigure lightdm :-)

Perhaps one of these might work for you too.

Greets,
Bart

2013/10/31 Alex Armani alex.arm...@rocketmail.com

 Hi folks. Happy Halloween! I've been ''playing'' with my system,
 installing the 64 bit Ubuntu Studio 13.10 distribution, and have ended up
 with the following:

 sda2 - ntfs, 181 GB
 sda6 - ext4, 73 GB
 sda7 - ntfs, 63 GB

 sda2 is my Windows 7 Home Premium partition, working perfectly.
 sda7 has no OS installed on it, and has been created because sda2 is
 getting full.
 sda6 has UB Studio 13.10 installed, but I can only login as guest. I can
 Ctrl Alt 2 and login as alex, so I know my password is being entered
 correctly, but then startx doesn't work.

 What I'd like to do, is copy all the contents of home/alex to sda7 then
 remove sda6, move sda7 so that it is next to sda2 and install UB13.10 from
 scratch.

 So I figure I can login as guest, CTRL ALT 2, login as alex, mount sda7,
 and then use a single cli command to copy everything in my home partition
 to sda7, but I don't know what the commands to do this are.

 I'm not looking to have my home partition on sda7, I just want to backup
 all my pics / videos /music / downloads so I can start again. I figured
 this would be easier than fixing the password issue.

 Any help appreciated; thanks in advance, from Alex.

Re: new to Ubuntu Studio

[bart deruyter]

If pulseaudio is the only issue, why not just use jack for recording
instead of changing distro?

  I'm migrating from Ubuntu 12.10 because of a horrible issue with
  pulseaudio I hope will not rear it's ugly head in Ubuntu Studio. The
  issue
  is the dreaded skipping problem.
 
 
  Haven't heard of it. What does it do?

 On certain audio chipsets (mine is an Intel) sound will randomly skip.
 this can even happen when recording -- which is causing me all sorts of
 headaches at the moment.

Re: [solved] How to use Inkscape? - objects and nodes

[bart deruyter]

I am sceptic too about workflow and ease of working to get to a certain
result but in my opinion though, many, if not most think in a strange way
about the tools and workflows offered.

It's like the discussion I've heard oh so often about synthesizers and
synthesized sounds, discussions about the most realistic and natural sounds
of which synthesizer. Synthesizers are synthesized, hence artificial
sounding by definition. If you want realistic sounds, buy a sampler go out
and sample the sounds from where they come.

The same thing counts for drawing and graphics in general.
If you want a real drawing on a computer, grab a pencil and paper and draw,
then scan it in.
If you want digital images, use your computer, fiddle around with vector
graphics or 3D graphics or even gimp, mypaint and equivalents.

Don't turn things around, and try to get a analog result with digital
tools, or a digital result with analog tools. I don't use my classical
guitar to create a techno beat. I use a sequencer and a drumcomputer and
neither do I try to create a classical guitar-tune using fluidsynth or even
linuxsampler... I grab my guitar and play it.

 PS: Nobody can pay for Layout pencils and the needed paper nowadays, but
 with Layout pencils you'll get a very similar result in a few minutes.
 Of course, such pencil drawings don't last for very long.

 So, I'm not against working with a computer ;). I'm just skeptic that
 Inkscape is ok. When I asked about apps that can replace screen tone on
 the US devel list, nobody knows a Linux app. If you ask for good NLVE
 the coders explain why we don't have it for Linux. So it's not a shame,
 since programing complex good apps is expensive and often can't be done
 by FLOSS, resp. programing a good app like Ardour2 did take a long time,
 some years ago Linux audio was unusable.

Re: [solved] How to use Inkscape? - objects and nodes

[bart deruyter]

Ralf,

A commonly used way is to let inkscape trace it automatically: path-trace
bitmap.

The results are not perfect, far from it, but it is a way to get a starting
point that is managable in combination with 'path - simplify' when needed.

I use that technique very often when I'm asked to make a poster and they
deliver the logo's of the sponsors in a way to low resolution (80px - 120px
for example). It has been a lifesaver numerous times.

When it's about shapes, I always keep the conversion to path as the last
part, the moment when it has to be deformed to 'not being a shape (square,
circle, star, triangle... ) anymore.

A lasso tool for selecting nodes would come in very handy indeed, though
with shift and drag-selecting I never really had issues. It are default
buttons in all applications when it's about selecting several items.

About inkscapes usability, I have used indesign and illustrator in the past
too (quite some years ago though) and I do find Inkscape easier to use.
Perhaps I should try a newer illustrator to check how they compare today
:-).

Grtz,

Bart

 If you need svg for icons you can't paint with a pencil on paper and
 simply scan it :(. After scanning an outline drawing, it's nice to work
 with an app like GIMP. Inkscape allows to draw Bezier curves, over the
 outlines you already have drawn and then scanned. I wonder if there's no
 way to automate this, instead of using tons of mouse movements and mouse
 clicks. Isn't there some kind of magnetic lasso for Bezire curves? Or at
 least some functionality as I described is provided by neu.Draw, where
 it's possible to add some nodes to objects as a circle, while handling
 those nodes also is easier, than it is for Inkscape. Perhaps Inkscape
 has got all that functionality, but I can't find it.

 Ralf

website to share jamming sessions?

[bart deruyter]

Hi all,

not ubuntustudio related, but I was wondering, apart from soundcloud, are
there any websites, dedicated to share jamming sessions? I've been googling
for it, but I mostly find websites dedicated to promoting finished songs
and albums... Soundcloud also seems to be more useful for publishing
finished songs.

Re: linuxsampler on UbuntuStudio?

[bart deruyter]

Maybe an idea, if the issue is only with the gig-file libraries
linuxsampler uses, and not the libraries concerning sf2, would it be
possible to create a build of linuxsampler that only uses sf2? That way
licensing problems could be avoided, while having linuxsampler in the
repositories.
Open sample files like those of the sonatina sample set, are often in sf2.

 Yes, kx-studio ppa. The licensing issue is with regards to the nemysis
 giga file technology. This sampler creates either sf2 or gig patch file
 formats.

 PS: Or does Linuxsampler play all kinds of soundfonts? IRRC fluidsynth
 does not play all kinds of soundfonts.

I replyed about this in your previous email about it. Did something get

what I wrote:

Aparently, due to licensing issues (I don't know the details), linuxsampler is

You do can get it from kx-studio's ppa though, that's where I get it from.

my story so far

[bart deruyter]

People,

I really get out of my mind from frustration, excuse me if I sound harsh...
it's the adrenaline still rushing through my veins...

About a month or so ago, I discovered the sonatina sample set. So I decided
to try it out. Guess what, it worked! Linuxsampler worked just fine,
jfantasia worked so good and I actually wrote some music with it.

Then the exams came along. So I had to study, no time to write music
anymore. OK, no problem, let's continue afterwards.

Today I took the step, and decided to fire up jfantasia.

guess what : It did not work anymore!

Connecting to LinuxSampler: Can't establish connection.

Here goes my creative moment AGAIN!

What does someone have to do to have a stable system? THAT KEEPS WORKING!

Yet again I had to spend hours and hours to figure out what has happened
with my system, and really, the only thing I want to do is MAKING MUSIC,
the only thing I don't get to.

When starting from commandline lscp uses a different IP then Jfantasia's
default connection setting, and I already discovered that the port should
be set to something else, like 8000 instead of  as entered in the
jfantasia default, because for some mysterious reason port  appears to
be in use for something else... and I don't even know what... netstat
--listen shows 'localhost:888', whatever that might mean.

Starting linuxsampler first with 8000 as port and then with the same
settings in jfantasia it finally works, but why the change in behavior? Is
it an update that caused all this?

Can someone plz explain to me why I have to dig into man-files listening to
ports, browsing forums, using mailinglists, only to end up so exhausted
from it that I simply don't get into doing what I want/have to do: MAKING
MUSIC? And this only a month after having a working system?

grtz,

Bart

Re: my story so far

[bart deruyter]

thx for your reply Holstein.

But sadly enough, for the real good sounding stuff, like the sonatina
sample set, which is wonderful, I am quite often forced to go outside of
the ubuntu-studio packages. If you know an alternative to linuxsampler for
using these samplesets (gig, sfz, ...) don't hesitate to tell me.

The problem seems to extend to rosegarden too though, which seemed to have
had an update too, and now all my midi channels are messed up. A channel
set to play strings (channel 2), now plays piano (channel 1),  even though
the tracks are set to the correct midi channels, and using my keyboard it
does play the correct instrument...

Yet another mystery to solve

I better give up for today... or I'm gonna start smashing things

 I don't update my studio machine. You are also using software there that
 doesn't ship with ubuntustudio. Getting envolved with testing the things
 you need can be helpful. I try and load up the test versions and make sure
 firewire works, since not a lot of folks use firewire, but we need to
 support it properly. I haven't installed 12.04 on my production machine
 yet, and I won't til I have time to install and test on another machine,
 then I on another partition or drive on my actual production machine. Then,
 I will likely keep the testing machine around to test big updates, or I
 just won't update that machine... I have daily use netbooks I keep up to
 date

Re: New to this list -

[bart deruyter]

That means a midi and audio capable DAW.

All of it in Ardour? That's new to me, well, with Ardour 3 yes, but without
a printable score. The official release isn't out yet... it's still beta.
It has midi support though.

Rosegarden does it all, and with a score. But I'm not a fan of it... I had
too many issues with it, but it might work out well for you.

My guess is, wait for Ardour 3 to release a stable version, download,
install (installer is really easy) and try it out. Then you'll have a
audio/midi recording app of huge quality.

If you can't wait, try the beta, but don't use it for real work, just for
testing and getting familiar with it.

grtz,

I'm getting the itch to start attempting to compose music. I'm looking

I'll start with just using the mouse and computer keyboard to layout

 the music.
Needs to be multi track (drums, guitar, bass, etc..). Once I get the
 tracks laid down, I may even hook my 5 string bass to the line in. If there
 is an application to apply effects to that, even more fun. But that's later
 on...

  I guess what I'm looking to do is compose  record to wav (the
 compress/convert to mp3) all on the computer. Eventually I'd try using the
 MIDI/USB keyboard to write some parts into the program.
I'm geussing I'd probably need a different application, if I want to
 add a line-in source to the song during mixing.


 All of this is possible using Ardour.

Re: New to this list -

[bart deruyter]

Perhaps we're getting off-topic a bit, but is there actually a midi
sequencer in the open source world that one could call 'fantastic' and is
as reliable as Ardour has been so far?

So far I've always bumped on applications that are buggy as hell, still in
development, unmaintained, limited in features or not able to follow new
technologies etc...
I've tried out seq24, qtractor, rosegarden, muse, I even tried openoctave,
but all have failed in my tests or requirements. Rosegarden came out best,
but as I said, with lot's of issues (latency in playback and recording,
crashes, it even manages to crash my XV88, which is connected with a midi
cable, softsynths that don't work, crashing my audiofire12 on exit...)

I'd love to hear about such an app.

About Ardour 3, it might be limited and look weird for midi indeed, but
when stable, it will at least be stable and do what it has to do, record,
edit and playback midi. Never recommend beta-stage software to
unexperienced people though, certainly not newbies in linux audio, and
certainly not to do real work, beta is beta and you can almost count on it
you'll have crashes, data loss etc...

For writing scores I use lilypond, a very steep learning curve, but superb
output,
even better then it's propietary alternatives that have a gui and drag and
drop system. Otherwise Musescore
is a good alternative, though it has some limitations.

grtz,

Bart

  All of it in Ardour?

 Ardour2 is for audio only and Ardour 3 for audio and MIDI. While Ardour2
 is the best software for audio, Ardour3 for MIDI still has got serious
 lacks. I'm an old school MIDI user from the 80's, for MIDI (with less
 audio) I recommend to use Qtractor.

  That's new to me, well, with Ardour 3 yes, but without a printable
  score. The official release isn't out yet... it's still beta. It has
  midi support though.

 Dunno which Linux app is the best to print scores, but Rosegarden is for
 audio, MIDI and MIDI score and perhaps one of the most used
 sequencers.

  Rosegarden does it all, and with a score. But I'm not a fan of it... I
  had too many issues with it, but it might work out well for you.

 +1

  My guess is, wait for Ardour 3 to release a stable version, download,
  install (installer is really easy) and try it out. Then you'll have a
  audio/midi recording app of huge quality.

 IMO at the moment the way MIDI is implemented is a little bit bizarre.

Re: [Announcment] Ubuntu Studio Community Wiki updated

[bart deruyter]

Hey,

looks great:-), congrats.
I'm considering to contribute to it indeed. Noticed some small
misconception. Lilypond is not used to write scores as if they were written
by hand. No application could ever achieve that exept mypaint with a wacom
tablet :-). It's used to write professional quality scores for printing and
publishing, with ideals and the quality of by hand typesetting of scores of
the old days in mind.

How far does the wiki go? I mean, what's the scope, limited to pure
technical stuff of software installation and hardware setup, or can it go
further, like actual tutorials about how to write a score in lilypond, or
how to make a simple/complicated song with some applications?

grtz,

Bart

 On behalf of the Ubuntu Studio Dev Team I would like to present the newly
 updated Ubuntu Studio Community Wiki, at:

 http://help.ubuntu.com/**community/UbuntuStudiohttp://help.ubuntu.com/community/UbuntuStudio

 All though this is a community driven Documentation project, the front
 page is now laid out to be more in the style of official documentation,
 with pointed out places for Ubuntu Studio users to contribute - the most
 obvious being the HowTo's section at http://help.ubuntu.com/**
 community/UbuntuStudio/HowToshttp://help.ubuntu.com/community/UbuntuStudio/HowTos(which
  could include anything from how to build your own kernel to
 converting audio files).

 Opinions are welcome, and also, contributions.

collaboration music

[bart deruyter]

Hi all,

I'm in the process of making an animation movie. I guess  I don't have to
explain it's really tons and tons of work. Right now I'm working on the
website to put it online, with all the necessary explanations and info, but
it is far from ready yet.

But, since it's going to be an semi-open project, (story is fixed, and you
could call it a life's work,  so I do consider me being the final judge in
what's going to be approved, but I guess that's obvious) I'm looking for
people and some tools to work in collaboration.
It speaks for itself that the final results will be freely available, in
that sense it will be fully open.

As far as text and images it is not that hard, but when it comes to music,
I haven't found really interesting things yet to work in collaboration with
others online, apart from ninjam, but that's more for jamming sessions.

I know it is not specifically ubuntustudio related, but are there people
with experience, knowledge or ideas on how to manage music composing,
recording etc. in collaboration with an online community? And are there
people out there interested in creating some movie music? Don't hesitate to
contact me, even personally, for more info about it.

Thinking about Ubuntustudio, this might be a way to test its capabilities
and a way to discover lacking features for this kind of work (comparing it
with Blenders open movie projects to pinpoint problems in Blenders feature
set). I mean, since Ubuntu and UbuntuStudio are the result of
collaboration, why wouldn't we jointly create some things?

Grtz,

Bart Deruyter

Re: rakarrack sync tempo with jack x-run

[bart deruyter]

Thanks for the info,

by testing, error and trial, it seems to be fixed so far by using jackd -c
s. I've figured out my chipset has no hpet.

I've edited a config file to give ohci1394 higher priorities since my
soundcard is firewire based. But it only had the opposite effect, strangely
enough, so I changed it back to it's default state.

I've managed to set the frequency scaling to 'performance' by default. My
machine is no laptop, so I think that shouldn't be an issue for the
temperature, apart from power consumption :-).

I also noticed rakarrack caused errors x-runs, just by handling it's
interface, moving a slider, clicking on a button. I don't know why, it was
no problem in the past. Anyways, starting jackd with -c s was a major
improvement so far.

Grtz,

Bart

2011/12/7 Gustin Johnson gus...@meganerd.ca

 hpet  is a hardware timer included on most machines since 2005
 (http://en.wikipedia.org/wiki/High_Precision_Event_Timer)

 This is generally what I use.

 You may also want to disable frequency scaling as I have noticed that
 xruns seem to occur when the CPU changes frequencies.  There should be
 an applet for that (there was under Gnome).  I use KDE which does not
 seem to have such an applet, so I wrote a quick little script to
 handle that.

 I also assume that you meant that you have already installed and tweaked
 rtirq?

 Hth,

Re: wacom fail

[bart deruyter]

I've been browsing around in the ubuntu forums, searching for a solution.
Apparently it is a Natty bug. There is a fix, but it requires quite some
patching.. and at the moment, I'm not up to it.

I actually am getting tiered of applying patches and fixes each time I
upgrade. If it's not wacom, it's my soundcard, if it's not my soundcard it's
my webcam.. and then there might be the wireless network card of which the
driver is dropped... It is becoming extremely tiresome. The sad thing is, if
I don't upgrade, I miss fixes that only can be applied by upgrading. Like my
soundcard. The midi port was only available since upgrading to Natty... but
then, it broke something else again.. sigh...

Instead of focussing on new things, Ubuntu should focussing on stability.
Usability by designing thought out user interfaces is fine, but only when
the machine can get to work properly. So far exactly that has never been the
case. I've always had a piece of hardware malfunctioning because of bad
configuration or broken drivers, modules and whatever more there might be.

  What can I do to trace the problem

 If you are using Synaptic and or doing backups, than

 - take a look at Synaptic's history. Was any Wacom related stuff
 upgraded?
 - compare Wacom related files with your last backup of the working
 studio.

 You can see Wacom related packages e.g. by using Synaptic's search.

 Are you using a xorg.conf? Did you upgrade the kernel? What DE do you
 use? I suspect GNOME2.

Re: Re: wacom fail

[bart . deruyter]

Be assured, I've spent about two months on choosing my drawing tablet and  
did even three months research to pick my audio card... The AudioFire12 was  
told to be 100% supported by FFADO at that time (it was about the only  
one). Apparently they forgot the midi port. Eventually it got fixed,  
indeed, but it needed fixing again, despite the fact they said it was 100%  
compatible. In the end you can only tell if it works when you have the  
hardware, research or not. And the fact remains that in one edition one  
thing works, another edition it doesn't any more, and then the next it  
works again, but something else is broken. This happens time and time  
again. On top of that once you get accustomed to a certain way of working  
to get broken things fixed, config files get moved around the system,  
that's exactly what happened to wacom, or there is a brand new system of  
configuring, using new naming conventions etc...
6 months is way too short indeed, should be at least a year cycle. Maybe,  
as I suggested in the full circle magazine, a combination of a rolling  
release, for software updates, and a yearly cycle for major system  
upgrades. That way there would be time to test the important changes, while  
people won't have to wait for updated applications.


I've got to draw, write, make music, model in 3D, not figuring out why I've  
got all those xruns all of a sudden, or why the pointer jumps to a corner  
of my screen when I click a button of my wacom. Now all of a sudden the  
lights (num lock, caps lock etc.. ) on my keyboard are gone.



Op schreef Gustin Johnson gus...@meganerd.ca:

The LTS releases are focused on stability as opposed to features. The  
releases in between are really nothing more than betas since 6 months is  
not long enough IMO to polish a release.


Having spent 15 years running Linux, I have learned that it really does  
pay to do some research before buying any hardware. It has been a while  
since I have suffered from badly behaving hardware.

wacom fail

[bart deruyter]

Hi guys,

This is really starting to extremely annoy me. I had an ubuntu install,
11.04, on which I installed the ubuntustudio packages. First thing I
noticed, was that my wacom (intuous 3) buttons didn't work properly. When
pushing the buttons and using the scroll pad's the mouse arrow jumped to the
top left corner. After a couple of months tinkering, and experimenting I had
enough of it, downloaded and installed ubuntustudio 11.04.

Guess what.. it worked! One day I had full control over my wacom. Today...
it's back to earlier. Again the pointer jumps to the top left corner of my
screen when I use any of the buttons. What did I do? I noticed the
compositing didn't work, even when enabled in compiz settings, so I
installed an app for 2-d unity settings, in which the button to enable
compositing does work. I've disabled it again, but the problem remains.

What can I do to trace the problem, and more important, to fix it? I really
can use these buttons in Blender, Gimp, Inkscape...

greets,
Bart

frescobaldi

[bart deruyter]

Hi all,

I've got a mystery over here.

I've reïnstalled UbuntuStudio 11.04. Actually, my first install was from a
regular Ubuntu 11.04, then adding the UbuntuStudio Packages. Before that, I
ran KX-studio, being curious, wanting to test it out.

Now, I've noticed some very weird behaviour in installing software.  I'm
talking about frescobaldi, I haven't had the time to test the other apps.
Frescobaldi 1.2 has the option to download and use the latest version of
lilypond. Now, this 'download' button did not appear in KX-Studio, using
Frescobaldi 1.2 . When I switched to regular Ubuntu 11.04, that button did
appear. Now I've reïnstalled the same Frescobaldi in UbuntuStudio, and I
guess that's even from the same repository from Ubuntu itself, no ppa's
added.. and that 'download' button has disappeared once again.

Question 1 : How is this possible?
Question 2 : How do I fix this?

I'm guessing there must be a library or something like that, which is
missing on a KX-Studio and in a UbuntuStudio install, but not in a regular
Ubuntu... but which library?

diagnostic tools to trace the reason xruns are happening?

[bart deruyter]

Hi all,

since recently I'm experiencing more xruns in ubuntustudio 11.04, more
specifically using the lowlatency kernel. My audiocard is an external one,
firewire, and I use the firewire driver. They just started happening out of
the blue, without changing anything significantly. These xruns happen
randomly, not caused by anything I do on the desktop. When I keep qjackctl
running without any audio apps open, now and then, about each half hour, or
20 minutes, there is an xrun.

My limits.conf file seems to be as described on the wiki's over the web, I
have 4 GB or ram, a duocore processor.. I see no reason for problems.
I've got a latency of 17.4 msec, with a setting of 256 Frames/Perios, Sample
Rate of 44100, and 3 Periods/Buffer. So far this was the most stable setup,
though I'm sure I should be able to go to 128 Frames/Period with my
AudioFire12. But I can't, more xruns happen when using this setting. Setting
the samplerate higher I get more xruns too. I'd love to record on 96000, or
even 192000, which is possible with the audiocard, but the computer system
prevents this because of these xruns.

This does make it unreliable for recording, which I want to do more
regularly and it makes me impossible to do recordings for others. I do not
want a system where I have to ask people to start playing again for the
recording because xruns.

So, I was wondering, are there diagnostic tools, test scrips, tracing tools
to get me to the bottom of this?

Grtz,
Bart

Re: diagnostic tools to trace the reason xruns are happening?

[bart deruyter]

Ralf,

thanks for the explanation. It does work better with the performance
setting. I do still get xruns when using midi though. Using sooperlooper, I
trigger recording with the pedal of my keyboard, through an usb2midi
misport2x2.

I guess the search for the PREEMPT_RT kernel is in place.. is there a PPA I
could use, or do I have to build it myself? Or is it the
linux-headers-2.6.31-12-realtime? I have it listed in the falk-tx ppa.

grtz,
Bart

  Next step, how do I change the governer from 'ondemand' to
  'performance'? I've never done that before, didn't even need to do
  that in the previous ubuntustudio versions.

 You can run

 sudo -i
 cpufreq-selector -g performance

 The better choice is to

 right click to the GNOME panel  Add to panel...  CPU frequency scaling
 monitor

 Once it is in the panel, left click to the scaling monitor icon and
 chose 'performance'.


 
  About the kernel :
  Weird, I keep reading from ubuntustudio that the generic kernel in
  Ubuntustuido 11.04 should be good enough, on the wiki with the
  comparing table I read better results from the lowlatency kernel.. and
  now there is the need for the preempt rt It is getting very, very,
  very confusing for me.
 
  but thanks for the help of course.. step by step, we'll get there.. we
  just have to.

 For kernels before version 2.6.39 and this version isn't supported by
 any repository jet, real-time optimisation only is done with kernel-rt.
 A kernel without RT can work too, but when you get issues, then use a
 kernel-rt.

 Hth,

 Ralf

 What architecture do you run, 32-bit or 64-bit and what is the version
 of the generic kernel you run?

 uname -a

 will show you.

 I can send a script that will build a kernel-rt automatically. Since you
 use the generic kernel, you could try the preempt only kernel for Ubuntu
 Studio. IMO it's better to use a PREEMPT RT instead of a PREEMPT only,
 but perhaps it works for you. Perhaps it's in a repository, see
 https://launchpad.net/~abogani/+archive/ppa?field.series_filter=nattyhttps://launchpad.net/%7Eabogani/+archive/ppa?field.series_filter=natty

Re: diagnostic tools to trace the reason xruns are happening?

[bart deruyter]

Hey, thanks for the script.. the kernel is built, and I've booted using it,
but I didn't test it yet. The nvidia driver does not work, but if I could
set my screen resolution correctly, that would be enough for me. I then
could switch between kernels for audio and graphic, 3D work. I hope I won't
have to re-enable the nvidia driver each time I boot into the generic
kernel, and disable it again when I boot into the realtime kernel.

The resolution of my screen is not listed in the tool provided for modifying
the resolution. It should be 1680 x 1050 at 109 Hz, but it's limited to 1400
x 1050 at 56 Hz.

Ralf, you mentioned the 2.6.39 kernel. You meant the real time features will
be included in this generic kernel? That would be wonderfull, no need to
have specialised kernels for it anymore, and with nvidia driver capabilities
:-D. I hope will be released in a repository soon.

Grtz,
Bart

 You can edit the script. It (nearly) only does, what you usually need to
 type manually in a terminal emulation.

 When the script runs 'make oldconfig' you perhaps only need to push
 enter for every question, but it would be better to read the output and
 if there should be something asked regarding to real-time, to answer
 carefully.

 The script is attached and reedited to fit to your setup, hence it's not
 tested for your setup, but it should work.

 Run

 sudo sh rt4us-natty

 Ralf

Re: Natty and the Real Time Kernel

[bart deruyter]

Hi all,

I've got the same result as Brian David. The generic kernel works quite
well, but has xruns, strangely enough, mostly when doing 'nothing'. So far I
had no xruns because of recording, mixing, using rakarrack etc... The xruns
seem to happen at random.

I do use Unity though, maybe there is something in there that asks some
processes which cause the xruns.

My soundcard is an external one, Audiofire 12. jackd is setup at 48000, 256
frames/period and 3 periods/buffer, at a latency of 16 msec.

Running the low-latency kernel eliminates all xruns... I'll definatly keep
using it, and I do recommend it too.

 get

 most
  of the time to not use anymore the RT kernel and all its related
 problems...
 

 I just installed Natty for the first time tonight.  This time around,
 I went with Xubuntu and installed the Ubuntu Studio packages on top of
 that.  As Scott mentioned, I needed to add myself to the audio group,
 but after this my equipment immediately worked.  Unlike previous
 versions, there was no need to change any configuration files to get
 access to my firewire device, which means that Ubuntu Studio is
 basically working out of the box for me now (or, it would be if I had
 installed from an Ubuntu Studio disc).  Yay!

 For a test run, I did some mixing on a recording I'm working on right
 now.  I started out using the generic kernel, and performance was
 surprisingly solid.  There were a few x-runs when starting up or
 switching between applications, but otherwise it was usable.

 I then installed Allessio's low latency kernel, and proceeded to mix
 for an hour and half without a single x-run, even when starting up
 applications and switching between them.  Rock on!  So, I can say
 definitively that the low latency kernel gives me better performance
 over generic.

 This test was run at 44.1 khz / 512 frames / 3 periods - getting about
 34.9 msec latency.  The next time I get the chance, I'll set up some
 mics and do a recording test at lower latencies (I'll push it to 128
 frames, which will take it down to 8.71 msec latency.  This is
 something I have been able to do previously using rt kernels) and see
 how it performs.

 So far so good.  Thanks for the work, everyone!

jack hangs when exiting apps

[bart deruyter]

Hi all,

Running Natty now, skipped a version, so previously using 10.04 but having
the same issues as before.

Let me describe, it is weird, but it is very annoying:

System :  UbuntuStudio 11.04, 4 GB ram, intel 6700 @ 2.66GHz, drive space
enough, nvidia graphics GeForce 7600 GS, external firewire audio card Echo
Audiofire 12, usb2midi 2x2 .

Problem : exiting some audio apps causes jack to hang.

Really weird, no xrun problem, no startup problem, but exit problem. I have
to logout, login again, and then I can start jack properly again.

Apps involved : Rosegarden, Qsampler, PD (perhaps more, but I haven't time
to try them all.

Apps that don't cause the problem : Ardour, Rakarrack, Audio plugins in
general.

The message says something about not being able to stop jackdbus...

Anyone else with this problem, or maybe with a fix?

thnx,
Bart

freebob - usb midi

[bart deruyter]

Hi all,

I've got a tricky thing to solve here.

Now I have a brand new Echo Audiofire12, it works perfectly for audio, but
sadly the midi port is not detected, though on the ffado website, the device
was seen as 100% compatible for ffado. I think this must be changed to 99%.

Luckily I have a midisport2x2, even though it has been reported not to be
perfect for midi recording ( a midi latency problem ), but I don't mind so
far, quantising does miracles, and I've always managed so far.

But now comes the real poblem:

Using ffado I cannot connect some software to my midisport2x2, because some
software (one major one, even pre-beta but anyway: Ardour3) only provide
midi ports for jack.

Is there a tool, or a way to setup jack so it uses firewire and alsa to get
my midi device listed in the jack midi tab?

grtz,
Bart

Lilypond + frescobaldi might be more difficult to learn indeed, but I
agree with it's quality. On top of that mscore doesn't have the
possibility to add tabs to your score (perhaps an svn version can, but I
guess it's not quite stable yet). Ok, there's tuxguitar for that, but
tuxguitar is not really ment for printing, more for displaying on a
screen. In my experience printing from tuxguitar is not good at all.
Perhaps the option is to keep lilypond installed by default,and add
frescobaldi (or have it at least in the archive).





The version of mscore that was installed in 10.04 by default was
very buggy too. Ironically I had to install a newer, unstable version,
to have it stable (dragging slurs caused crashes). So it was actually
useless to have it installed by default in the first place.

As I've voiced to the other developers in IRC, I also see Lilypond +  
Frescobaldi as the best notation software for those who want to write  
anything complex (though guitar tabs isn't really even that complex). I  
have added a workflow, which includes Lilypond and Frescobaldi, to the  
wiki page where all of this is being hashed out - AND I ENCOURAGE  
EVERYONE TO ADD TO THE WIKI PAGE to get more processes and veiwpoints  
involved in this development process. Bernard, for instance should  
probably add a workflow that includes Common Music if that task isn't  
already taken by a superior program or other workflows (maybe even if it  
is).




Without community involvement adjusting the wiki page a lot of the  
suggestions in this e-mail thread will fall to the dregs of past history  
without full consideration by all developers. Please add your ideas to

Re: After updating to ubuntu studio, lost sound.

[bart deruyter]

Hi,

what happened to me :  I had an update yesterday, did not reboot, and sound
kept working. This morning I started my computer, and I had no sound either
in pulseaudio. Pulseaudio could not find any devices. Using jack I could
have playback in music apps, like lmms and ardour, but no input.

Fix was a bit weird, but worked perfectly :

In the list of apps to start on boot, one of them is pulseaudio. The command
shown was 'start-pulsaudio-x11'. I changed it to 'pulseaudio', without the
start and x11 part. I logged out, logged in, and things worked perfectly
again.

Turns out, when pulseaudio is not running, input channels are muted, so I
could not have any input in jack.

I have no explanation for this. I do must admit I have falk-t-j's repo's to
have jackd2 in lucid. Perhaps that has something to do with it.

Grtz,
Bart

Re: video stutter

[bart deruyter]

Thanks for the responses.
(I first accidentally answered with this to one individual accidentally, so
I guess it didn't get on the ubuntu-studio-users list, now it's solved (so
far it is at least) I repost a modified version :-) )

I have this problem with proprietary and open formats. Flash version is
10.0.45.2. Like many, I have discovered this has the 'buttons are not
accessible with mouse' bug when compiz is running, certainly on youtube.

After some testing, and looking around, I found the problem, it was linked
with the nvidia driver. For some mysterious reason, I think it must have
been because of an update, it used the 173 version, not the 'Current
Version' (has no number). I changed to 'Current Version', and the problems
are solved.

As a side note, I started testing my wacom ( intous 3) and the buttons don't
work anymore, while they did out of the box in US 9.10, so that's something
else to work on in the future. I only discovered it now, so it means I don't
really use these button very often, but any how, improvement, is
improvement, it should work. I'm just learning programming and am thinking
about working out a GUI for the wacom settings, but I can't promise anything
at the moment (got to have time for it).

 Hi all,

 Running ubuntustudio 10.04 I seem to have a lot of trouble with the
 playback of video. At first I thought it was a slow internet connection when
 playing flash video online, but it happens on local video, all types of
 video, from mp4 to mpg2, flv, mkv...

 Mostly trouble starts after pauzing for a while. I had this problem before
 when playing from a DVD because the content has to be read from the disk,
 that's normal I guess, but now it always happens when playing files on the
 harddrive too.

 For online video it is really a problem, because on short video's I even
 can't see any motion anymore. Playback of audio is not stuttering though.

 I have found a bug in the ubuntu bugtracker that could be compared with
 what I experience, but there seems to be only one other person affected by
 this : 
 #572580https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/572580. 
 The difference is that my audio does not have difficulties. Perhaps I
 should file a new bug for this.

 Is there anyone who has a similar problem, or even a solution for it?

 grtz,
 Bart

video stutter

[bart deruyter]

Hi all,

Running ubuntustudio 10.04 I seem to have a lot of trouble with the playback
of video. At first I thought it was a slow internet connection when playing
flash video online, but it happens on local video, all types of video, from
mp4 to mpg2, flv, mkv...

Mostly trouble starts after pauzing for a while. I had this problem before
when playing from a DVD because the content has to be read from the disk,
that's normal I guess, but now it always happens when playing files on the
harddrive too.

For online video it is really a problem, because on short video's I even
can't see any motion anymore. Playback of audio is not stuttering though.

ubuntu studio and me menu

[bart deruyter]

Hi all,

first time I ask a question myself here, though I've been following, and
learning a lot from this mailinglist for a couple of years now. :-)

I just installed the 10.04 Ubuntustudio, congratulations, so far I haven't
had any problems yet. Even my scanner, that used to need firmware, manually
configured in a config file, now works out of the box, for the first time
ever!!

I have a little problem though, it's not essential to get it working, but it
would be fun.
There are some new features promoted on the ubuntu site, one of them is the
'me menu' for social networking. I don't seem to find it anywhere. Can
someone help me in getting it working, because I do find it an improvement.

grtz,

Bart

Re: Wacom intuos 3 in karmic

Hi,

mine worked out of the box, right away after installing Karmic, but I did
do a fresh install, not upgrading through synaptic.

 Hello all,
 Does anyone have a wacom intuos 3 tablet working in karmic?

 I have made some progress thanks to this thread :
 http://ubuntuforums.org/showthread.php?t=967147highlight=wacom+howtopage=40but
  The stylus has no pressure sensitivity for some reason (in gimp and
 incscape). The eraser however does and everything else seems to work as it
 should do.

 *I have* configured extended input devices and set them all to Screen by
 the way.

 Any help would be much appreciated,

 Thanks,

 Robin

 Hi everyone,

 never used this mailinglist before, though I've learned a lot by

 I use a Dlink, quite an old one I think, wireless card, with an ACX111
 chipset on it. It shows, using lspci, but it doesn't show up on my list of
 cards in the network tools. It's weird, because in 9.04 it worked out of the
 box, as soon as I had it plugged in.

 I don't know if it's ubuntu.. or ubuntustudio related, but there seem
 very few, or even no messages about it on the forums.
 Anyone else with this problem?

 If someone can help, it would be very much appreciated.

 Bart,

 Have you installed netowrk manager?  It's on the disks but not installed
 by default, and I believe it may have some wireless libraries that could
 help you out.

 No luck with it Eric, thanks for the tip though. I'll continue the search
 tomorrow. In the mean time, I'll watch out not to stumble over the cable
 :-p.

 greets,

 Bart

I now did find in synaptic, that there are
linux-backports-modules-wireless-karmic-server and -generic packages, but
not rt.
Perhaps, there's the issue?

Re: recording vocals

[bart deruyter]

Hi,

microphones have nothing to do with compabilitiy with Ubuntustudio, perhaps
for usb-microphones, yes, but for recording, regular microphones are used
that are connected to a soundcard. I use this setup :

microphone - mixer - soundcard - computer(ubuntustudio)

you could also try :

microphone - soundcard - computer (ubuntustudio) if you don't have a
mixer.

With this I mean that you don't have to search for a microphone that could
be compatible with ubuntu studio, regular (non usb) microphones have nothing
to do with software.

greets,
Bart

Re: Where is the music made in Linux?

[bart deruyter]

Hi,

On Jamendo artists can add tags to describe the software they use. I've seen
lot's of open source applications in these tags, like Ardour, Rosegarden,
Audacity Perhaps something to look into :-p. Maybe these people can be
contacted for representation on a list, or for asking their opinions on the
software they use.

Re: Newbie question: Gnome desktop

[bart deruyter]

Christian,

it is very simple:

go with your mouse on the top bar, rightclick, and select add panel or
add bar or something like that. (I've got the Dutch version, and it's
called 'paneel').

Greets,

 Hi guys,

 Whenever I've used Ubuntu in the past, including Ubuntu 9.04, there
 has been a task bar at the bottom of the screen, showing each running
 window.  This is in addition to the bar at the top of the screen
 containing the launch menu, the system time, etc.

 However, in Ubuntu Studio 9.04, the bar at the bottom of the screen is
 absent.  Google wasn't any help in figure out how to make it appear.
 Any suggestions?
