LiSa .track/.sync in Chuck 1.3.1.3
by Simon Steptoe 06 Dec '12

06 Dec '12

Apologies if this is documented somewhere, but am I right in thinking that the .track/.sync functions are currently not working in the latest version of Chuck? Anyway, put it like this... the LiSa-track example files are working fine for me in Chuck 1.2.1.3 (on Windows 7 machine), but with 1.3.1.3 I'm just getting silence. Thanks Simon

Hi, I'm trying to use neting/netout but without success. I keep getting undefined type 'netout' I tried the examples from https://chuck-dev.stanford.edu/svn/chuck/trunk/examples/net_send.ck since they are the only ones i could find with netout chuck version: 1.3.1.3 (chimera) OS: gnu/Linux Distro: Archlinux Thanks.

no such file or directory
by hhazel＠gmail.com 03 Dec '12

03 Dec '12

I'm new to this program and list, but I have searched through the archives without finding a similar problem. Whenever I try opening a .ck file, i get this error message "[filename]: no such file or directory". So it recognizes chuck, but it seems like chuck just doesn't recognize .ck files as its own. I have Windows 7, 64bit. Maybe Chuck isn't compatible with this system yet? Your help is greatly appreciated. daniel

module chugen
by Michael Heuer 30 Nov '12

30 Nov '12

I knew I was going to get to this eventually; I have always wanted to be able to ChucK a ugen to a parameter, similar to control voltages in modular synths I suppose. With this public class Module extends Chugen { Gain _cv; { _cv => blackhole; } fun float tick(float in) { return tick(in, _cv.last()); } // subclasses override this function fun float tick(float in, float cv) { return in; } } I can do this, which interpolates the cv to a frequency between 2.0 and 8.0 class SinModule extends Module { SinOsc sin; { sin => blackhole; } fun float tick(float in, float cv) { Interpolate.linear(cv, -1.0, 1.0, 2.0, 8.0) => sin.freq; return sin.last(); } } and then this, which uses a SinOsc at a frequency of 0.25 as the cv to modulate the frequency of the SinModule which modulates the gain for a tremolo effect. class TremoloModule extends Module { SinModule gainLfo; SinOsc rateLfo; { 1.0 => gainLfo.sin.gain; gainLfo => _cv; 0.25 => rateLfo.freq; 1.0 => rateLfo.gain; rateLfo => gainLfo._cv; } fun float tick(float in, float cv) { Interpolate.linear(cv, -1.0, 1.0, 0.0, 1.0) => gain; return in; } } SinOsc sin => TremoloModule trem => dac; 0.4 => sin.gain; 220.0 => sin.freq; 1::hour => now; https://github.com/heuermh/lick/blob/master/examples/moduleExample.ck I am wondering if others have cleaner ways of doing this, because this example isn't even easy for me to follow. michael

Chuck mode for emacs?
by Bunny Blake 29 Nov '12

29 Nov '12

Hi all, I'm new to Chuck, and searching for the Chuck mode for emacs (chuck-mode.el). I've seen it referenced in a couple of places, but all of the links to it I can find are dead. Does anyone have a copy of this which they could mail or host somewhere? Thanks!

Re: [chuck-users] OSC function crashing Chuck?

Stefan Didn't get any error messages... and tried removing the @ as you suggest but to no avail. However, your suggestion did prompt me to look through the examples files in more detail and by adding a "Machine.remove(oscProcess.id());" to explicitly remove the shred waiting on the OSC event... everything sorted itself out.

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

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!
