Thanks for the feedback, Mr. Off. :-)  Seriously, I really appreciate 
it.  (responses interleaved below).

Fast machine!   This means you can use big voice numbers, like 64 (if 
you can find a use for that kind of polyphony).  Alternatively, you can 
throw up multiple [polywavesynth]s and/or [polygrainsynth]s, for 
polytimbral polyphony, or fattened unison voices.

This is in [polywavesynth_example] -- good catch; I'll fix it on the 
next release.

This is such an excellent idea, I implemented it immediately (changed 
the sliders to log).  Not nearly so much shift-dragging is necessary 
now.  You have to watch out for attack/decay/release values of less than 
11 msecs. or so, though.  They can sound very clicky (although this may 
actually be desired in certain circumstances).  Again, this will be 
available on the next release; it's easy to change on your own, though, 
and it has no ill effects.

I don't understand what you mean here...the gain slider on the 
[polywavesynth] UI is interacting with the attack?  Are you sure it's 
not clipping - it's easy to clip with higher gain settings.  The more 
notes you hold down, the higher the output, so for big polyphony, you 
have to bring the slider down a bit.  If I'm totally misreading what 
you're saying here, let me know.

> 4) would be nice to have more control over the amount of panning.

Like all the controls, it's available via OSC:

[an lfo, or anything else you like]
 |
[/example/pan/position $1 <
 |
(connect to the rightmost inlet of [polywavesynth])

Similarly, you can change the pan lagtime with a message like 
"/example/pan/speed 0.8". The OSC implementation of [polywavesynth] 
(polygrainsynth works the same way) is here:

Re: [PD] [polywavesynth] and [polygrainsynth] bug fix

[hard off]

yeah getting some quite lush sounds out of this polywavesynth now.  says its
only using 4% of my cpu as well, which is a bonus.  haven't tried the grain
one yet.

a couple of things:

1) the message box going into the sssadpanel currently contains
[example_presets/example1(
but the folder is actually [Example_Presets], my system doesn't work with
the change in capitalization.

2) it's hard to adjust the ADSR sliders at low values.  particularly for
attack, it is important to be able to choose values around 20ms or 50ms.  so
i think a log, or exponential scaling would be better for the ADSR sliders.

3) i had a look, and i can't figure out why, but it seems that the global
gain is still somehow affecting the sound further up the chain.  ie..when i
adjust the global gain, the attack of the sound is also changing.  still not
sure where this is coming from, but maybe something connected to the adsr?

[PD] [PD-announce] The OtherSide Server is DEAD!

[Ilias Anagnostopoulos]

The OtherSide server died a couple of hours ago... Hardware failure! It 
refuses to boot. It was experiencing some RAM problems and I tried to 
fix it by replacing the RAM with a stick of the exact same specs. This 
somehow managed to fry the motherboard. It does not do anything anymore.

This means that you will no longer be able to get anything from the APT 
repository (PD-extended and more) and you will not be able to access the 
SVN Repository, until this is fixed.

I hope we will have no data loss, since the hard disk should not have 
been affected by this. I will try to find a replacement server as soon 
as possible. If I don't find one by tomorrow, I will try and host things 
temporarily here and there until a permanent solution can be found.

Anyone willing to offer server-space (temporarily) or an actual server 
machine, please let me know..

Thanks Josh,

The full code for this is located at the SVN repository of the OtherSide 
server (http://otherside.servebeer.com/software/otherside/). I did it by 
using a machine as a dedicated headless server. I installed Ubuntu Linux 
Server-edition, installed Apache2, Icecast2, Festival, IRCD-IRC2 and 
CGI:IRC from the repositories, and installed X11 and PD-extended.  The 
PD-side of things is basically a synthesis engine listening for OSC 
messages. The Apache server hosts the website from where you access 
everything. The Icecast streams the audio in the form of an 
internet-radio stream, receiving the source from the mp3cast~ PD object 
(Unauthorized Library by Yves Degoyon if I'm not mistaken). The PD 
patches do not use a dac~ since I'm not interested in having sound in 
the headless server.

So PD listens on two different local ports, one for OSC, and one for raw 
data that is strictly not OSC. I created a Python IRC-bot, that works in 
a similar fashion to an infobot. It sits on a chatroom and listens for 
messages. When it receives messages it can understand, it forwards them 
to the appropriate place. When it receives messages it doesn't 
understand, it forwards them to the port that PD listens for raw data. 
The raw data is actually ASCII data from the text in the chatroom, which 
PD translates to MIDI pitches.

If you send a message preceded by the word "osc" then the word right 
next to osc acts as the "path" and the numbers next to it as the values. 
These can control midi note velocity, duration, effects, signal 
processing and so on. This information is forwarded by the Python Bot to 
the PD port listening for OSC. Other OSC commands control a wavetable 
oscillator going through effects as well.

If you send a message preceded by the word "talk", the bot writes 
everything after "talk" to a buffer, which is fed to "Festival", the 
speech synthesis system. Festival performs a text-to-wave conversion, 
and "talks" what you've written. PD then plays back the "speech", going 
through effects controlled by the OSC.

I like the idea of the IRC because it's an old-and-trusted method of 
on-line interaction of several people, with built-in functions to 
support exactly that. No use in re-inventing the wheel. The actual idea 
is that people can create their own chatrooms where the Bot can be 
invited, for a specific "sound" or "phrase" or "experiment", or 
interaction with other bots. For instance, you can create a chatroom, 
connect your own bot to it, which reads OSC directly from an OSC 
controller such as the Lemur, and pipes it to the IRC channel for the 
OtherSide bot to read!

Then you also have chatrooms for people to just talk about experiments, 
without the bot being present so without the discussion altering the 
sound, unless desired!

The two distinctive strong points are the ability of IRC servers to 
connect to each other forming "networks", which essentially share all 
chat data, and split the network traffic to many servers, only needing 
to share control data between them, since the same sonic output is 
generated on each server by this data! The other point is that unlike 
projects such as NetPD, users do not need to have PD or any specific 
software installed on their computers, they can work directly from their 
web-browser through CGI:IRC (platform-independent). This also solves the 
"latency problem" of collaboration of many people in the same room, 
since only ONE machine needs to output the sound that ALL of the people 
work on creating.

This was actually my Master's Thesis, I've written a paper on it 
available from the website I've mentioned, including block diagrams and 
configuration files.

I might package this at some point, although it is going to be quite a 
massive package. Let me know if I you need more explanations on the 
paper or anything like that. Feel free to download the source and try it 
out, it's GNU GPL licensed.

Sounds doable with synthesized audio.

When building a "play list" like function that handles virtually an 
infinite number of audio files, I think what Roman referred to as 
"Symbol table pollution" comes to consideration... I imagine this being 
unreleased memory that occurs in the course of handling file names.
Is my understanding correct?

I was able to build xsample, flext, and py per Patrick's instructions
in UbuntuStudio 8.04.1.
When building py I got a couple of errors initially, but when added
the numpy packages all went well

[PD] Pd as a 24/7 Icecast/Shoutcast source client (alternative)

[Ilias Anagnostopoulos]

Hello,

I haven't seen the whole discussion about this, but from what I 
understand someone is using PD, mplayer and jack for streaming to an 
icecast/shoutcast server.

I have used PD as a 24/7 source encoder/streamer, using mp3cast~, in the 
OtherSide project. This was a server that had PD running a synthesis 
patch which can be controlled by OSC through IRC and a bot listening on 
a chatroom there. It has been up for the past 3-4 months non-stop and 
with no maintenance within the University of Sheffield intranet.

My initial experiment was to run PD through Jack and use Darkice. I'd 
patch the PD outputs to the Darkice inputs, which would then stream to 
the Icecast server. It didn't seem to be as stable though and it was 
more CPU-heavy than mp3cast~. I initially tried to do that cause I 
wanted to use other software apart from PD, but I ended up scripting the 
rest of the software and get their output in PD, which would pipe the 
output directly to the Icecast server. I didn't use a dac~ or jack, 
saving a lot of CPU resources.

Any comments welcome, I'm still interested in hearing about ways other 
people do similar things.

Take care,

Ilias

to access the posterize subpatch in [pt.layerfx]?

Alternately, can anybody give me advice on how to create a posterize patch

nono... it's only, that i am not even using pd to playback the sound,
but mplayer piping the sound over jackd to pd. pd starts mplayer
instances with appropriate flags through [shell], so that mplayer
instances connect to pd on individual jack ports. the problem with that
approach: sometimes mplayer hangs, which makes whole pd hang or at least
impossible from within pd to stop mplayer. a typical situation is:
mplayer can connect, but stream buffer is not filled and as long as it
is waiting, you cannot send commands to mplayer, thus also no stop
commands, so you have to kill it through another [shell] -> this
sometimes kills not only mplayer, but the whole pd process. working
without [shell] mess seems to me much more stable.

the reason why i use mplayer for the playback - and not pd - is because
it supports basically any audio format you can think of. that was an
important goal for the radiosolarkompass project.

the logs, I noticed a lot of IP's actually asking for the APT, so I
thought I should let you know just in case you experience any downtime.

Because Miller's dolist is already long, and nobody wrote the patch for
multi-level undo yet, and submitted it to the patch tracker. Oh wait,
the desiredata guys wrote that UI feature (along with hundreds of
others), but it was heavy with other changes and part of a slow, buggy
build of Pd, and I don't think there was a huge amount of interest in
submitting changes back to Miller, and he probably wouldn't have
accepted them anyway.

Hooray for community! ;)

aah yes, but the point is, you moved one extra object accidentally and so 
have lost the selection of everything - and the ctrl-z only undoes the last 
one extra object.

someone smarter than me with c and tcl/tk should really implement this.

Re: [PD] text2d for japanese, persan and other languages

Hi again,

Just to say thank you, it's working !!

But now I hav to convert a few thousand of word in unicode.

So I think the best is to make a parser from a text file to unicode...

but mappings are very complex ... I think there is maybe some  
utilities to do that on the web ...


I will hav a look ..

all the best,

have a look at http://lists.puredata.info/search/PD-list?query=string+text3d

the trick is to convert your string into a list of unicode values
(integers). (actually the values are not unicode but the glyph-id  
within

the font; but usually this can be assumed to be unicode)

for experimenting, this might be a good start:

nevertheless this is usually not true with Gem.
Gem is openGL based, meaning it uses hardware acceleration.
off-the-shelf gfx hardware has been highly pushed by aming industries,

[PD] [PD-announce] Flext/grrrr Seminar @ IRCAM (Paris, France) - Dec. 2nd

[Arshia Cont]

For those of you in or around Paris:

Tuesday 2nd of December 2008, 15H00, IRCAM,  Salle Stravinsky

A seminar by

Thomas GRILL, Media artist

on

"flext: C++ programming layer for cross-platform development of Max/ 
MSP and PD externals"

(in English)

For directions: http://www.ircam.fr/5.html


Abstract:

Flext seeks to represent a uniform programming interface for  
extending the most common modular real-time audio systems Max/MSP and  
Pure Data (PD) with external modules, or short externals. These  
modules provide a way to tailor such a system for one’s special needs  
and supply additional functionality. Source code based on Flext is  
able to exploit nearly all features of the respective real-time  
framework while staying completely independent of the actual host  
system and platform (hardware and operating system). flext currently  
supports PD for Linux, Windows and OSX as well as Max/MSP for OS9 and  
OSX and Windows, and other systems can follow in the near future.

In this seminar, we look at the current status, possibilities and  
limitations of Flext, a review of some famour objects developed using  
flext, as well as hearing your exotic wishes.

implement multi-level undo in pd.tk

j/k

but seriously, why can't we multi-level undo yet?

do your fonts support arabic and japanese glyphs?
rectangles are the usual indication for glyphs not available.
there are lots of ttf fonts out there, many of them not providing more
than ISO-8859 characters.

you might have to use [string( messages rather than [text( messages to
Gem's text-objects to properly input unicode characters (due to lack of
input methods i never managed to directly use higher unicode characters;
but it might well be possible)

since you approach required both an abstraction and a specially named
subpatch on the parent, why don't you just copy the code needed directly
into your abstraction? no dynamic patching required whatsoever :-)

afaik the fonts findable by Gem, pdp and other libs and the fonts
findable by Pd itself are 2 different things.

Gem for instance manually opens fonts and it does so via Pd's
open-via-path feature (which searches all the searchpaths).
if the specified font (file) does not exist, it will not display anything.

Pd otoh, does not use fonts at all, rather it asks(!) its graphical
toolkit (tcl/tk) to use a certain font which delegates this request to
the system. if the requested font is not available, the system will (or
should) provide a font that is reasonable close.

so Pd should automatically find bitstream-vera-sans-mono file if it
exists on the system.

but of course this is does not help with the initial problem.

btw. here the font-file is located at
/usr/share/fonts/truetype/ttf-bitstream-vera/VeraMono.ttf.
but since i usually don't use Pd-extended (and don't have it installed
right now) i am not sure whether PdX would really find it (though afair
i never had a problem)

[PD] strange readsf switch as abstraction

[Hans Roels]

Hello,

If you use readsf~ connected to two subpatches with switch~ in an 
abstraction it doesn't work. If you open this file as a main file 
(not as an abstraction) it works fine. If it is used as an 
abstraction it starts to work from the moment you move or connect an 
object 'downstream' of readsf~ (while the file is 'playing'). From 
then on the readsf~ and switch~ work well.


Have a look at the file in attach, I can't explain this or am I 
missing something?

start jack
start Ardour
in Ardour change synchro source from "internal" to "jack"
start pd (the audio engine can stay off)

send bangs to the jack_transport object (with a metro e.g.)
you should get the playhead position in samples

nice!
i am interested in controlling ardour markers with osc
what i would like to do:
- change the position of an audio marker
- delete a marker
- add a new marker at a given position
- get the playhead position (u can have it with jack_transport but it
compiles only on POSIX systems)
- set the playhead position

hi pat,
it's possible to compile pyext
the main problem i found is to properly set the flags for the
compilation of flext

nano buildsys/config-lnx-pd-gcc.txt

i  disabled all flags at the end of this file

compiled flext
compiled pyext

some notes are available here (in french)
