OSC function crashing Chuck?
by Simon Steptoe 25 Nov '12

25 Nov '12

Whilst working on some OSC stuff, I got to a situation where Chuck (and mini-Audicle) kept crashing at the end of the main shred. I've stripped out all the Ugens and synthesis stuff and am left with the following algorithm (see below) as the culprit. At the end of the 5 seconds duration of the main shred, Chuck crashes. Take out "oeGetProcessId => now;" and all is fine. Now aside from whether it's a viable/good piece of code or not, I was surprised that it goes so far as to crash the system. Is it a bug... or is it me? (Code below). Simon Steptoe //CODE ============================================== OscRecv RecvProcess; 32000 => RecvProcess.port; RecvProcess.listen(); RecvProcess.event("/process/id, i " ) @=> OscEvent @ oeGetProcessId; Shred oscProcess; spork ~ oscProcessingIt() @=> oscProcess; 5::second => now; fun int oscProcessingIt() { int testValue; while (true) { oeGetProcessId => now; if( oeGetProcessId.nextMsg() != 0) { oeGetProcessId.getInt() => testValue; <<<"Hello from PROCESSING: ",testValue>>>; } 0.1::second => now; } } //============================================ Thanks Simon Steptoe

OSC
by Romain Michon 21 Nov '12

Hi List, I'm totally new in the Chuck world! I'm trying to use the OSC examples provided at http://chuck.cs.princeton.edu/doc/examples/osc/ and both chuck OSC_send.ck OSC_receive.ck and chuck s.ck r.ck don't work on machine. In the first case, OSC_send.ck seems to send correctly the OSC messages (it returns sent (via OSC): 0.895094 ...) but OSC_receive.ck never get them. r.ck runs the sine wave oscillator fine but never receive the messages sent by s.ck. I didn't make any change to the files (except for the path to the audio file in OSC_receive.ck, of course ;) ). I tried to send OSC messages to both OSC_receive.ck and r.ck with SuperCollider and PureData without any success. OSC works fine to communicate inside and between these two programs though. Am I missing some flags/options? I'm running chuck on Ubuntu 12.04 64bits. Thanks a lot for your help! Cheers, Romain

Hi all, Just a heads up about a performance and workshop happening in the next couple of days in Toronto: 1. At 10 PM Sat Nov 10 at the Tranzac Club (292 Brunswick St, Toronto, closest subway: Spadina) the Cybernetic Orchestra - the laptop orchestra at McMaster with an emphasis on live coding will be playing a set as part of the 416 Improvisers Festival. 2. From 2-5 PM on Sat Nov 10 I'll lead a free public workshop on live coding in ChucK at a downtown Toronto location yet to be announced (I'll send a late-breaking update on these lists). The workshop will emphasize the kind of nimble, responsive coding performance we try to develop in the Cybernetic Orchestra!

ChucK code search, an experiment!
by Tom Lieber 28 Oct '12

28 Oct '12

I'm interested in experimenting with some code search algorithms on ChucK code, but I need a lot of ChucK code to test them on! How might I go about obtaining such a collection? GitHub doesn't seem to recognize ChucK as a language, nor does SourceForge (why did I check there). Seems like my best hope is to spider the wiki, mailing list, and forum for .ck files, but it'd be great to hear about other options. :) -- Tom Lieber http://AllTom.com/ http://infinite-sketchpad.com/

AES convention, San Francisco
by David Ogborn 26 Oct '12

26 Oct '12

Hi all, I'm here at the 133rd convention of the Audio Engineering Society (AES) in San Francisco and wondering if there are other EA / laptop orchestra / live coding people here. Get in touch and we'll go for a beverage or meal or something like that! (Shameless plug: I'm here presenting a engineering brief/poster, this Monday at 9:30 on the EspGrid software developed to facilitate sharing and synchronizing in laptop orchestras. The software has been incubating in the Cybernetic Orchestra for the past while, and will be publicly released very soon...)

Re: [chuck-users] forever => now;
by Perry Cook 24 Oct '12

Yep, hack the chuck source, or... As with so many of use do with quarter, eighth, etc., Just add a one line definition at the top of your ChucK file(s): 100000000 * week => dur forever; // effectively forever or another alternative: Event forever; // if this is ChucKed to now, but never thrown, then it's truly forever Yer pal, PRC On Oct 24, 2012, at 9:00 AM, chuck-users-request(a)lists.cs.princeton.edu wrote: > Send chuck-users mailing list submissions to > chuck-users(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck-users > or, via email, send a message with subject or body 'help' to > chuck-users-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-users-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck-users digest..." > > > Today's Topics: > > 1. a strange idea (David Ogborn) > 2.

a strange idea
by David Ogborn 24 Oct '12

24 Oct '12

Hi all, While preparing some sample code for the Cybernetic Orchestra, I hit upon a strange idea I thought I would share with this list. What if there were an instruction/built-in function in ChucK that yielded control forever? A lot of sample code has something like this in it: while(1::minute=>now){} It would be elegant if this could be written like this: forever => now; Or something like that! eternity => now; // ? eternity; // ? eternity(); // ? I fully realize that this is violating the perfectly valid principle of "if it ain't broke don't fix it"!

Anyone familiar with URBI?
by Josh Adams 20 Oct '12

20 Oct '12

Hi all, hope everyone is doing well. I came across this Universal Real-Time Behavioral Interface thing and found it pretty exciting. Couldn't help but immediately think of how amazing it could be to use with ChucK somehow and wondered if the community has had any experience with it in the context of ChucK or elsewhere (a cursory chuck-users list search didn't turn up any results so here I am...) http://www.urbiforge.org/index.php/Main/Tutorial http://www.conscious-robots.com/en/reviews/robots/urbi.-universal-real-time… http://www.gostai.com/downloads/urbi/2.7.1/ Cheers, Josh

Hi! The release note says '(added) Chugins: dynamically loaded compiled classes/ugens - see http://chuck.stanford.edu/extend/ for examples.' but the link seems to be dead, does anyone know if it had moved somewhere else? Thanks, fweth
