Yes you can multitrack very well with high latency with external monitoring, however there is really no need to do that as UbuntuStudio will do well at lower latencies even with 12 or more tracks with jack at 32/2 (which is where it happens to be just now with 17 tracks).

When I play a 80 kHz sine it is audible audible, you say hmmm But maybe here we misunderstand: you mean, a, say: 1KHz sine with 80KHz samplerate right? No I mean playing a 80 kHz sine (with a 192kHz sample rate) I made a number of sines with audacity and played them with VLC among other players, VLC produces ghost sounds with sine waves above a certain frequency. So paying music with VLC in that format makes you hear things you never heard before, great! Pity that the difference is fake and distortion rather then more music information. r a player, that is made to play distributed audio as - something very different. It is far below 20 kHz and clearly audible on 10 Euro loudspeakers, so it is definitely not 80 kHz. I would say ditch it or use it for things that doesn't matter but not for playing high res or quality audio. Quality audio is 16/44.1 CDDA, carefully mastered and dithered from recordings, that may or may not be recorded at higher rates. Whether it is required or not to use higher sample rates for perfect audio reproduction is another discussion. But at the moment there is no such thing as a perfect audio system. So claims as 44.1 kHz or MP3 is enough holds no water. MP3 or OGG is not enough at all. The difference is clearly audible when you compare it with a uncompressed stream of original recordings. Commercially matered material is stripped down often anyway so the compression does not make great differences but it is perfectly feasable to record, mix and distribute audio in a way, that uncompressed PCM does sound quite different than MP3 or OGG of the same material. But 16/44.1 is hard to beat and 16/48 is not. I, BTW, have ditched the 96KHz experiments and use 48KHz with all great results and 9 out of 10 professional Studios do the same. The dutch concert hall records in SACD format Interesting, so they do not use PCM but Delta-Sigma-Modulation in the first place or do they use 24/192 PCM and interpolate later? Anyway: one fine day when more than 0.1% of the listeners out there own a SACD-drive or when anyone out there is eager to play DSM-streams on a computer, I guess VLC will adopt. Oh and yes it does so under windows too. Whatever rate you use, the input and the output of any of the audio interfaces people have tested has been 20-2Hz. I experienced, that it does make a difference, when a lowpass at 20KHz is applied but 48KHz deliver 24KHz and anything beyond that is indeed irrelevant. Distortion and noise have a real impact when HiFi is concerned, frequencies, that are beyond the double of human hearing do not. Well it is no so simple to determine what the human hearing is capable of in the first place and show me the first audio set on which I cannot hear the difference between a real cymbal and a cymbal played on that audio set. The effect is even more apalling when you compare a distorted Guitar from a Marshallstack with a recording of it. And the reason is physics: any speaker is just a simulation, it can create soundwaves, that have more or less the very same characteristics as the original, very very complex soundwave made by an instrument in a room. But they cannot be the same: 8x12 inch of speakermembranes that have no other obligation but creating a blast of metalguitars cannot be perfectly mimicked by a pair of 8-Speakers, that has to produce Bass, drums and singer also... So there may be more to do to bring more of the real thing to the homes of the audiophiles. But I doubt, that higher frequency-ranges will help. In my experience Ardour works perfectly well with PCM of any samplerate. And I would not bother to play such recordings using a player, that is made for average distributed media. On the contrary! I am happy to have a player like VLC, that will reveal whether I did something wrong when rendering a file for end-user distribution. best regards HZN Edmund -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel

So a capable Player should be installed with KDEnlive anyway as you must be able to play your own rendered files and the clips you make them from. If posting them to a video site like Liveleak, Flash in the browser is also needed, to check that the upload works. The videos I make are done like this: 1: copy the folder containing AVCHD videos from the camera card onto the desktop and name it 2: Open Kdenlive, save a blank project in the new folder 3: Use Gnome-mplayer to play clips, looking for the good ones. Totem can lock up Nemo/Nautilus on a drag and drop, so I usually use Mplayer for this job. Xine is hard to drop clip after clip into, but ALL the players are somewhat buggy for this. 4: Drop the good clips into Kdenlive, set up the timeline 5: Add backing music to the timeline. Use Audacious to sample backing music if not already decided-or mplayer to play a music video which can also provide backing music 6: Render .wav audio, 720P rescale, full 1080P in that order, using H264 codec at 2000 for 720P, 6000 for 1080p 7: Use Avidemux to replace the bad audio track (dropouts) Kdenlive gives rescaled files rendered from AVCHD right now with the .wav track, saving as copied video, AAC audio in MP4 container, do this only on the 720P as the fulleres file has good audio 8: Use qt-faststart from the command line ro remake the final files into web optimized MP4's with the headers up front. 9: Play the files, check for both human and machine errors! 10:: Post the 720P to Liveleak, then archive both rendered files on both primary and backup disks On 06/03/2013 at 8:18 PM, Len Ovens l...@ovenwerks.net wrote: On Sun, June 2, 2013 11:58 am, Hartmut Noack wrote: Am 02.06.2013 17:23, schrieb Len Ovens: In the mean time, Parole (like thunar) has been fixed and works on anything I have tried it on.

In fact a documentation of the video work flow for those starting out in video creation would be fantastic. As I wrote before I got caught of the conception of VideoSongs which is format for doing music videos with two rules: 1. What you see is what you hear (no lip-syncing for instruments or voice). 2. If you hear it, at some point you see it (no hidden sounds). So, when recording my music I now also set up my iPhone to record myself recording the music. This is later cut to a VideoSong. For an example check out http://youtu.be/lBUUOJpFg9Y which was the song that made me discover VideoSongs. Good stuff, thanks for sharing! When I have finished the song, editing and mastering I go to work to make the video: 1) Import all the record videos into the video editor. For now I use Kdenlive, but will learn Cinelerra as well to see if it might fit my process better. I doubt that. Cinelerra is useful, if you want to work with material for theatre-screens or if toning is exceptionel important for you. But since KDEnlive is stable and reliable, I do not longer see an important reason to wrestle with a beast like Cinelerra 2) Import the actual song. 3) Since I also use a one-take-only policy on my recordings I don't have to sort out which take of which instrument I used in the final song, there will be only one video file for each instrument played. I do more and more abandon presets, even those, I made myself. One take only is quite a challenge though... ;-) 4) I have sync all the videos to the music file. To do this in Mac or Windows the video editor often support scrubbing, so you can pinpoint the audio in the current video with the same spot in the song. Kdenlive does not support scrubbing so I have to look for obvious things in the track, like certain words sung or when an instrument start to play. Just orientate by the waveforms and you get it perfectly in sync. Since your videoclips are shot at the very recording you can align the audio of the videoclip and the mixed-down song just perfectly... This I can do visually and also by zooming in on the graphic display of the audio in the song and recorded video. This step takes some time and need to be done for each track. Otherwise later on in the video it will start to get out of sync and look bad. Once everything is lined up I can mute or delete all the audio from the video files and only hear the original song audio. 5) Then the cutting begins. I'm quite basic so far in my editing so it's mostly just simple cuts between the different instruments, a couple of fade in fade out, some 'picture-in-picture' clips and such. 6) When I'm happy with all the different cuts I add an ending screen since my goal is to put everything up on Youtube. It will contain some information about me, the song and a couple of pre-views of other videos I've made. Later on I will edit this part in Youtube to add links to the different videos, subcribe link and so on. 7) Next I render to a format that will make it look good on Youtube. I use downloaded Render Profiles downloaded from within Kdenlive. So far I haven't made any other rendering, to save it for future use. 8) I then check the video in different players and with different computers and OS to make sure it is in sync and no glitches in video or audio have occured while rendering. 9) If I'm happy with it all I upload to Youtube. Case closed. This is by no means a professional workflow but it's what I've come up with so far. What I miss is a simple way to get all the video clips in sync with the music and an easy way to do 'picture-in-picture'. I have found a way to make the pic-in-pic sort of like I want it to look but it's a bit tricky and takes a long time. I've seen tutorials on how to do it on other platforms and video editors and it's very quick and simple. Perhaps Cinelerra might have an easier way to do this, but I haven't had time or knowledge to figure it out so far. /Jimmy -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel

This has been a disappointment to those studying bats who have been unable to find any computer audio interface that supported any higher frequencies. So I am wondering where you would be getting an 80kHz sine wave from that is output from a computer. A higher sample rate than 48000 does give a smoother bandpass frequency response and allow a simpler HF roll off filter to be used. However it also introduces the very real possibility of high frequency foldover into the audible pass band. Yes many studios use high res audio, but it is not because it is measurably better. It is because the clients demand it because bluray supports it. Many studios record at 48000 (the standard BTW) and upsample to meet whatever format the client demands. The higher rates are IMO gimmicks to sell new versions of old movies and of course the equipment needed to support it. There are some audio cards that do sound better at these higher rates, but they still do not include higher audio frequencies than the low 2 Hz range. It is merely a matter of the roll off filter being designed for that rate and it not working quite so well at the lower rate. A card designed for the lower rate can sound just as good.

Also many of the MP3 players or CD playing SW do not play well with Jack. (I don't know any) That is my experience too. Once jack is started and the pulse-jack-bridge runs, all audio-trouble is gone. Any sane audio-application supports either Jack or PA automatically. And I cannot see, that the PA-bridge increases the rate of xruns(as of now I have zero of them while experimenting with Guitarix and Qtractor and watching YT-videos as well (*videos *with* audio that is...). It should be easier to disable PA to a near-removed status though Unload module-jackdbus-detect: pactl unload-module module-jackdbus-detect PA still takes up memory, but uses almost no cpu without that module. The CPU-load would be tolerable, the problem is, what PA+dbus do at startup. Is there a way to blacklist interfaces? Some command like : PA do not touch that device!? best regards HZN -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel

This describes what I do occasionally for many hours without any crashes with KDEnlive. Regarding the professional workflow that is in fact just the usual workflow I presented both CinelerraCV and KDEnlive to a filmmaker, who is a friend of mine. He makes Movies for Cinema and TV, has studied it to the full at Babelsberg. He told me, that both programs work fine for him as long as cutting is concerned. He also told me, that the material edited in these Programs would need to be processed on more professional gear for toning/retouching the lighting. He also told me, that he never ever would consider to do the latter on his Mac, thats a job for dedicated workstations he stated apodyctically. And he was quite impressed how much one can do for the soundtrack when working with Xjadeo and Ardour. Btw. the myths that Blender is everything that's needed to make 3D animations is also nonsense. In addition not only a NLVE is missing, but also some other options, e.g. automatically lip sync (at least it was missing, I don't know if they have included it yet). Try to find out, what other NLVE was used in making the Blender Movies, especially Mango: I fail to find those tools in the project description: http://mango.blender.org/about/ They only mention free software on Linux, though shamefully get the music from external sources that use whatever else AFAIK Blender can be and is used for professional and good home videos, but it's just one production tool of many production tools. It is used to produce full-fledged Motion Pictures that look much more professional than many commercial Movies released on DVD. Unlikely that I'll have that kind of films you're talking about. If I watch films made in the USA, than more or less only films from people like the Coen brothers, Jim Jarmusch etc. and I usually don't own those films on DVDs or any other media. But again, first of all it's a myth that many films were produced using Linux only Feel free to believe, what you was programmed to believe(to have a Futurama-Quote at last in this thread ;-) ) and second, I'm talking about software that, with certain qualifications, can be used at home, at least with better home PCs. Try KDEnlive, just as is, without all the tweaking, it just works. For me claims that Linux is professional, is the more out of reason for people who prefer averaged Hollywood movies, In terms of craft Avatar or LOTR or Cloud Atlas are the reference. No country for old men is a reference too for its genuine 80ies feel but many movies like Ghost Dog and the like have their qualities in photography, play, script and so on, in technical terms they are simple. If you have a photographer, actors and script in the league of Ghost Dog or Blue in the face you can make such movies and cut them on Linux with free software. averaged chart music. For the kind of art I like to do, at least for music, I can use Linux, but for people who want to do this mainstream stuff, all the tools are missing. We for example don't have auto-tune for Linux. You talk about the middle-class, not the top-notch. The latter care for songs, skill and personality of musicians, concepts and ideas to produce albums that last. And the technical aspect how to record comes last. Some of the greatest recordings of the last 20 years where recorded onto analogue tape, some on 4-track machines, some even on 2-track. All much less than a Linux-computer with a Hammerfall running Ardour. Back to the topic ;). I guess KDE 4 can be used to provide a sane work flow for audio production, but Unity and GNOME 3 don't provide a common work flow for this task. Xfce, LXDE, KDE = sane. Unity, e17 and GNOME 3 = insane. Insane is a bit harsh but the wording aside I agree. However, the work flow to make a home video in a Roland Emmerich style, does differ to making a home video in a Jim Jarmusch style. The latter is much easier, that is correct. The same for audio, e.g. The Black Eyed Peas differ a lot to Motor City Hardrock from the 70s. Different musicians, working differently, that is all. The flexibility to provide the fitting workflow is in the producer, not in his/her software. Rockbands still work today, in new ways and in the old ways alike, many of the best 70ies-Rock Albums are made in the last 5 years. And of course they do not use Ardour. Because Ardour on Linux is not a product. Mixbus is one, and so it is used. That is the difference: not quality, reliability or flexibility, The question is just: is it a product that is acclaimed in the industry. And: is there a product with even more acclamation (got Sequoia, but Protools could be more of a product right?). best regards HZN -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com

Ths is much more than I get before when discussing this bug(expect from FalkTX, who did his best to help me out) I haven't seen this bug before, but it does seem like the card is already being used by something - maybe even another jack? indeed there was jackdbus running when I encountered this but killing it did not help. If you want to help solve it, make a bug report, and try to find out the cause of the problem as well as you can. It's the best chance of someone learning how to fix it. This is excellent advise and I am *NOT* ironic: find out what happens and fix it is the way, I try to go with this bug for about a year now. In several fora and lists. And, let me rant for a little bit.. First of all, Ubuntu Studio is not a pro audio distribution. Please: if it is not, then it is nothing but some skin for Ubuntu. It is perfectly acceptable, that it is not tweaked to the limits (RT-kernel etc) but I am sure, you will agree, that if Ardour does not work normally on it, what remains to make it any special? It's for all multimedia content creation. So simply removing pulseaudio is of course out of the question This I agree, the charme of US is the compromise between real-world Desktop and Pro, good way to go and perfectly possible methinks. - but I'm considering making it configurable so that one can choose not use it, or even not to install it in the first place. More to come on this in the future. In any way, the installer will have more options than today. There is no strict central planning involved in developing Ubuntu Studio. Only in areas where it is found necessary. Which means, if you want to do something for Ubuntu Studio, and it doesn't break anything for anyone else, you are free to do it. Not everyone is adept at fixing issues in pulseaudio and jack code, so one cannot expect the team to only work for that. I hope I'm making a point clear about this. This I am aware, the percentage of coders who actually can fix bugs in these delicate beasts is not that high. Thats why I mentioned the PITA-thing: the more people speak about these problems, the more motivation to fix them for those who can. No complaints - no problem - no fix. That simple. best regards HZN Further, people who don't care about pulseaudio will of course not care about fixing problems with it at all. So far, I've been able to add upstream fixes to jack and pulseaudio by adding patches to packages. As a new member of the Debian Multimedia Team, I will also start to work on improving the actual packages that we import from Debian - as, we don't actually package them ourselves, which some have been led to believe. There are some issues that I would like to look at, among other things how jack is packaged, and also, how realtime privilege is administered. My goal is to make any Ubuntu flavor just as easy to use for multimedia (including pro audio) content creation. So, making Ubuntu Studio work well on all DEs is not a bad goal. And the people who find that interesting will be the people who do the work. Simple as that. This goes for all areas of interests. I find this to be a good democratic way to go about developing a community Ubuntu based flavor. It will also shine a light on all the issues that exist on different DEs, and will enable us to come up with generic solutions that can be applied

As far as other desktop environments are concerned, part of me is in favour of this mindset being adopted (as I've never left gnome despite Ubuntu Studio's switch to xfce - I just don't like that DE). If a modular front end was adopted then it would encourage wider usage and a better overall design. However, what Hartmut may have been trying to state was that this is development is probably not the best use of developer's time. There have almost always been stability issues, bugs, and lack of documentation in Ubuntu Studio that the user sees as more drastic to their workflow than annoying quirks from the given DE. So yeah, apply force to the major problems, Exactly. Anyway, the problem is, that (no offence meant) there are more people out there, that can tweak and script desktop-stuff than coders, that are deep enough into the low-level affairs to be able to fix the real annoying issues... So if that can be helpful: I am perfectly satisfied by the US-Desktop! I like it, whenever I test it, I do not find anything that would need repair. Even though I use KDE for my day2day work including working with Ardour3, Guitarix, KDEnlive, testing Stuff like Bitwig and most new music-related software for Linux. I run it on Ubuntu and its KDE and USs XFCE are both just great. Good job, people! but it would be a prudent philosophy to reduce the amount of xfce-specific code that ships with the distro. We don't know how long into the future the xfce platform will best suit our needs (very little warning was given during the gnome/unity move that prompted our switch to xfce in the first place), and the lack of DE-specific code the easier it will be for those of us who love a different DE to just switch. Most wise. Productive work should be supported well by the DE but it should not depend on a specific desktop. BTW: If I compare stability and performance of Ardour3+many plugins + Guitarix under KDE, XFCE or Fluxbox I fail to see any practical impact of bloat. Non of the 3 setups is enough to fill more than 2 thirds of my 8Gig RAM, that are a lot to me but not that special nowadays. And on my other machine I run comparable setups with 3Gigs RAM and with not much difference either So performancewise I do not think that a DE needs to be tweaked a lot.

There are common workflows for pro-audio work and even while I could add a list of odd things, caused by Xfce, it's a sane choice to use it as the default for Ubuntu Studio. I'm using it on other Linux installs too. Pulseaudio is something that should be discussed.

IMO it's already annoying if I need to start an app by it's name, but to kill it by killing python, however, this at least makes sense, while this qjackctl.thingy is an exotic Ubuntu Studio unique thing, that IMO isn't well thought out.

Re: Making Studio work with more than one DE
Am 22.05.2013 22:09, schrieb Jimmy Sjölund: Hi, this is my first post to the mailing list. So bare with me for a short introduction. When I discovered Ubuntu Studio some years ago I only had access to a very old pc and a quite old laptop. However I was able to record some songs on it, but mixing was a nightmare since the computers were too old. Then I upgraded to a Sony Vaio after much research about Vaio and Ubuntu. However, there were issues between jack, my audio card and how the Sony Vaio use USB. The result was that I could only record in 16 bit, 44.1 kHz. Which was worse than I had before on my old computers, 24 bit and 48 kHz.. So I reverted to Windows for my audio recordings and tried out every new release of Ubuntu Studio until finally everything just worked in 12.04. At last, I could actually do all my recordings, mixing and mastering in US. But by then I was about to have my first child and the time for recording somehow disappeared... Anyway: any person, that uses Win or Mac for that that tries US and is encountering this problem will switch back and maybe consider using Linux next year or never Which was just what I did. I was persistent to try out every new release until my equipment finally worked. By now it's outdated, oh well, but that's another issue. Do you have a statistic on how many people out there use US for music-production? This would be interesting. From reading the Ubuntu Forums there seem to be at least some using it in their professional studios. I do music recordings, but the degree of professionalism could be argued. On the other hand, with the DIY revolution in the music industry many could be labelled professional. First of all, Ubuntu Studio is not a pro audio distribution. It's for all multimedia content creation. I have always considered US as a pro audio distribution, why not? Real time/low latency kernel and all... I see now that site actually states multimedia in several places. But if I wouldn't use US for pro audio, what should I use instead? Back to Windows or Mac? Further, what defines pro audio? Probably in the music industry ProTools on Mac and so on will continue to be leading, but for a home studio or in the early stages studio I think Ubuntu Studio could be a choice to consider. And more with the right marketing and support. Mind you, being an audio engineer and musician I'm mostly thinking about the audio parts of the distribution. (Though I happily use Gimp and Kdenlive). Getting audio working for audio production, with some bloated desktop environments is not very useful. I couldn't agree more. I like when my desktop looks nice but when I'm about to record, cut a video or handle large graphics my main concern is performance. Mine is time, thats why I use to spend 1-2 E more when shopping for hardware -- I buy the performance to spare the time tweaking a feeble computer into a powerhouse-workstation. And for my day2day job I want a desktop, that offers all I need in less than a second as I need it. And I want a real-world Linux desktop because I want to keep an understanding for the average end-user. I write for Magazines that are for such users and to be experienced with a custom made tweaked Super-Linux does not help much to walk in the shoes of such normal users. And it works great for me. Whenever I get in trouble it is because of misconfiguration or misbehaviour of software, never because of the natural demands of that software. It could be, that for some critical live-recording I would switch to Fluxbox and kill all the background-services I use to have running normally (LAMP, Networkmanager etc) But not for editing or for recording overdubs. I was quite happy when US changed to Xfce. I think it's the right way to go. I actually changed my other workstations to Xfce as well after that. XFCE is perfectly OK but not primarily because it is leaner than UNITY or GNOME3, but because it is more simplistic and it does not need 3d. KDE would have been a good choice also, because it can easily be configured to be even more lean and simplistic than XFCE. And it comes with a better file-manager. But again: XFCE is good. best regards HZN If you want Unity or other you can always use standard Ubuntu and add the audio, video and/or graphic tools you need. Make Ubuntu Studio a bit special for the creative people. But: We don't know how long into the future the xfce platform will best suit our needs (very little warning was given during the gnome/unity move that prompted our switch to xfce in the first place), and the lack of DE-specific code the easier it will be for those of us who love a different DE to just switch. Which also makes sense. Please remember that the team is only a handful of people, and constructive help in most cases is actually doing things yourself. I'm currently trying to get more people involved, and we have gotten some responses. Many

Thankyou for your comment. I can not work on your problem for a number of reasons. The first being that with two computers and 5 different audio interfaces, I have not had that problem. So for me to work on it, you would have to ship your system to me so I can work on it. You do not need to fix it, I would consider it a major improvement and call you a sage, if you could only tell me, what could be the actual reason for it. I suspect, that I could find a way to fix it myself and share this fix with the world if I only would know wehre exactly to begin I was even grepping thru /etc in the faint hope to find that config-file that has something related to that message. It is a part of PA, so much I did find out: http://git.0pointer.de/?p=reserve.git;a=blob;f=reserve.txt so it is PA in collaboration with dbus. Do you know a place, where I can find the documentation how dbus is configured to run PA in Ubuntu? And if it turned out that this was an upstream problem, I would have to ship your system (or sound card) upstream to someone who was willing to work on it. You know and I know, that this has nothing to do with my hardware. I run this gear all day perfectly OK once I have started it by un/replugging the interface several times. And I can reproduce the problem at will. It is a matter of software, software-setup I guess. Second, I am not a coder. I can do shell script (bash, tcl/tk and some python) and a bit of c, so long as time is not a consideration... in other words I would not even try to look at real time coding or anything that needed special libs. That stuff right now is beyond me. C++ just doesn't make sense to me, I can use some of the GUI stuff by following examples, but I don't really understand what I am doing. Third, this is not a paid position. That is not how community projects work. If this was a commercial project, the first thing that would happen is they would hire someone better than me. Second that person would have specific goals such as you ask. But in the community based project, volunteers look around for what they can do and what interests them and do it. That is what I am doing. I do also do ISO and install testing as well as some (very little right now) recording. So I know that for my systems jack (and pulse) both work. Speaking of community, as you are a part of it and have a special interest in the problem you have, perhaps you should start there. What some of us can do is help you understand where to start, and what steps to take. (welcome to the team) Ahhh: OK, OK: if you can *promise*, that you can make the above mentioned failed to start kind of thing disappeare for good, I would provide a nice US-Menu and some documentation too for running US under KDE. And half a dozen Wallpapers How much are you willing to pay for this service? For these promises? Ohhh sorry for that I thought delivering a working system was your promise anyway, I only asked for a promise to not forget that. How much of a wage are you willing to pay so that we can hire some coders to fix your problems? This is a volunteer project, we are happy when people do something productive that moves the project forward. Last time I checked, reporting bugs was considered something to move a project forward. So I expose to you my bug, you crush it, get the fun and the fame. To increase the motivation I am willing to work for you by providing a solution for you latest project: running Ubuntu Studio in another DE. So you got the time to find a coder who actually *knows* what part of Pulse

It's not incredibly feature rich, but I've found it to be very stable, lightweight, and it handles huge files better than anything else out there. Best, Marc I second that strongly - MHW is the fastest, most stable editor I know for usage with jack - undispensable :-) HZN -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkmJumYACgkQ1Aecwva1SWOG0wCfT2H978TNyodoBzqTL2Z3R+CX dC8AnR3y8EtNr3nmM1MqiiIMe14PrzzC =nILZ -END PGP SIGNATURE- -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel

Very very important: LV2-support in Ardour and CALF and Invada Plugins as well as SWH/LV2 - these are revolutionary. Also I do not know, why Specimen is not included by default, it is the most reliable/configurable softsampler I ever used on Linux so far. At the other hand I would drop Bristol - I never saw this synth working OK anywhere (ist the same on Fedora and Suse) so I dont think, that it should be included for it only casts frustration upon beginners - it should be available in universe though...

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Cory K. schrieb: manager, has been removed. :) Specimen the sampler, I *think* wasn't included because the case was made for another already included app. Well: Specimen does not use any popular /proprietary sample-lib format but its own (loaded WAV-Files organized via a simple XML-file), so it is nice and open and at the other hand quite off-mainstream. But it works flawlessly and very, very stable with jackd so I would strongly opt for it. best regs HZN -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkmHlOcACgkQ1Aecwva1SWOvmACfVz8VxeWdY/Mz6xVEdnlvy11j OUcAn1JviRPB/x+ZOEqPo9KV2bmHdUHV =fC52 -END PGP SIGNATURE- -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
