embedding ChucK, and Windows8, ARM, etc.
by Rob Fielding 02 Mar '13

02 Mar '13

I am using ChucK on an x86 based Windows8 large multitouch screen; as nothing more than a way to create a multi-voice OSC synth that I can describe to users how to install (at minimal cost) and get setup (with little expertise on their part). But Windows store apps (ARM, sandboxed - like on iOS), forces generally conspire to have you try to embed everything into a monolithic process. So: 1) The GPL licensing (SuperCollider as well as ChucK) seems to be an issue for anyone trying to host ChucK embedded into a controller process. Is this an actual problem, given that we are generally just linking in unmodified build of the sources? 2) What is going on with the future of ChucK? After tinkering around with the options for making an OSC synth to match my controller: 1) visual spaghetti code (Pd), 2) An ugly language in wide use (SuperCollider) 3) Hard (CSound) 4) Nice but not well known (ChucK). 3) Performance. I saw Ge Wang say that performance isn't a priority for ChucK, but have no idea what the practical implications are. Will there be (and do there need to be) target specific optimizations to take advantage of SIMD, and other ways of meeting performance goals, especially in the more constrained ARM environments? I haven't tried to do an ARM build of ChucK and get it installed onto Surface, but I read that you can't in general freely communicate between processes on localhost for store apps anyway (ie: OSC over UDP localhost); so that leads back to the problem hosting ChucK as an embedded library. -- http://www.youtube.com/rrr00bb http://rfieldin.appspot.com http://rrr00bb.blogspot.com

Dealing with String objects?
by Wolfgang Gil 09 Jan '13

09 Jan '13

Hello chuckers I am looking for a reference to the 'string' object class in chuck. I am having a hard time trying to guess what methods are available for the class. I also recently came across with the StringTokenizer object but it seems to work only when the token is a white space. Is it possible to assign a different token to the object? here is what I am working on UGen uArray[3]; new SinOsc @=> uArray[0]; new TriOsc @=> uArray[1]; new PulseOsc @=> uArray[2]; for(0 => int i; i < 3; i++) { <<<getType(uArray[i].toString())>>>; now + 1::second => now; } What gets printed is the object's type plus what I believe is a reference to memory that I am currently not interested in, separated by a colon ( TriOsc:1001f36a0) Happy holidays! -- http://www.wolfganggil.com <http://www.wolfganggil.com/about>

chuck output to console on stdout
by stephane.poirier＠oifii.org 13 Dec '12

Hi All, Here below are 3 lines of code in chuck. How could I modify it to output the value of T in the chout? // this synchronizes to period 0.75::second => dur T; T - (now % T) => now; // output to console on stdout chout <= 1 <= " foo " <= 5.5 <= IO.newline(); Regards, Stephane

LiSa question
by Aurélien Bondis 10 Dec '12

10 Dec '12

Hi, I'm trying to figure out how to have multiple samples of different sizes looping together. I think I kind of have it but would like to be sure :) Are the voices here for that? Record does not have a voice option, so I understand that I have to explicitly tell my sample what part of it is supposed to be 'voice 1' or 'voice 2'. Also in my code, I seem to have my voice2 starting from something like 1second before its end and then loop, did I miss something ? Here is my code: --------------------------------------------------------- //a simple signal path adc => LiSa saveme => dac; //gotta tell LiSa how much memory to allocate 60::second => saveme.duration; saveme.recRamp(200::ms); <<< "recording 1" >>>; 1::second => now; 1 => saveme.record; 3::second => now; 0 => saveme.record; // Set voice 1 start and stop to use in the loop saveme.loopStart(1, 0::second); saveme.loopEnd(1, 3::second); <<< "recording 2" >>>; 1::second => now; 1 => saveme.record; 10::second => now; 0 => saveme.record; // Set voice 2 start and stop to use in the loop saveme.loopStart(2, 3::second); saveme.loopEnd(2, 13::second); // set voice 1 to loop saveme.loop(1,1); // set voice 2 to loop saveme.loop(2,1); <<< "playing">>>; // play loops saveme.play(1,1); saveme.play(2,1); while (true) { 1::second => now; } ------------------------------------------------------------ Thanks for your help. Aurélien.

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
