granular music recommendations?
by AlgoMantra 23 Jul '24

23 Jul '24

Yo All....I'm trying to download and study some of the best music out there which features granular synthesis. I haven't heard much yet beyond Iannis Xenakis, but I'd love to know what your favorites are. Perhaps it would be worthwhile putting up a torrent of the same. If possible, kindly provide links to mp3 files or any other type of free downloads. (What do you think of Jaron Lanier's music?) http://www.jaronlanier.com/musicdownload.html cheers! ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

is there a way of doing "callbacks" ( i.e. passing function as argument to be called later ) ?
by henrique matias 08 Jun '12

08 Jun '12

This is a question Chris did to me and it reminded me some related questions i forgot to ask: Is there a type "function" or type "Class" ? Is there anyway for "evaluating" a string to chuck code in order to do dynamic calls ( like javascript "eval" function for instance ) ?

a little debugging help for frozen VM!
by [chriswicks] 30 May '12

30 May '12

Hey, all. I'm attempting to build something that shifts layers of ChucK files based on OSC events, and I hit a snag really early on. I'm a relatively new programmer, so hopefully this isn't too stupid of a question, but I've got an issue that freezes the virtual machine and doesn't play any sound or send any OSC events. Nothing happens..the VM shows that the shreds are added, and then it just freezes and I have to force quit...it won't take a --removeall or --kill command or anything. Individually, each file works as it should, aside from the file whose code I am including here. I think I may be missing a key concept as to the way Machine.add works and how it assigns the value of the shred to an int, but I'm just not sure. If anyone can give me some direction here as to what might be happening I'd appreciate it! I've tried advancing time in various places, setting my initial pedCount to various values, all to no avail. Thanks very much, and please let me know if this is unclear in any way. //begincode Machine.add("justa.ck"); //class of frequency definitions Machine.add("pedestrianSender.ck"); //OSC sender of int values OscRecv receiver; //OSC receiver object 6449 => receiver.port; receiver.listen(); receiver.event("weather/pedestrian, int") @=> OscEvent pedEvent; -1 => int b3base1; //int to store a shred ID -1 => int b3base2; //ditto 25 => int pedCount; //int to store pedCount sent via OSC while (true) { //if the pedCount is greater than 20 (a value which will be sent via OSC) and b3base1 is equal to -1, i.e. the shred isn't currently running, //add both shreds to the VM and assign their shred ID to the b3base1 and b3base2 if (pedCount > 20 && b3base1 == -1) { Machine.add("b3base.ck") => b3base1; Machine.add("b3base.ck") => b3base2; } else { //if the pedCount is less than 20, remove both shreds from the VM and assign -1 to their value so that if the pedCount goes back above 20 they //meet the conditional. if (pedCount < 20 && b3base1 != -1) { Machine.remove(b3base1); Machine.remove(b3base2); -1 => b3base1; -1 => b3base2; } } while( pedEvent.nextMsg() != 0) { pedEvent.getInt() => pedCount; 2::second => now; } } //endcode

noob: change ADSR release/floor value
by George Locke 21 May '12

21 May '12

Hi, I am trying to make a simple FM patch. I want the modulation index to change by ADSR, but I'm not sure what the best way to set the ADSR's gain to a range besides 0-1. (I am new to ChucK, but not to computer music and not to computer programming.) The signal path I have right now looks like this: SinOsc m => ADSR modEnv => Gain g1 => SinOsc c => dac; m => Gain g2 => c; If I set g1's gain to maxIndex - minIndex, and g2's gain is set to minIndex, I achieve the desired result, but I just want to make sure I'm not making my life unnecessarily complicated by doing it this way. (I'm used to max/msp where there's a +~ object.) Thanks, George

Space Navigator
by Lester Hall 21 May '12

21 May '12

Hi folks, I bought a Space Navigator and would like to interface it to ChucK. I tried writing a joystick program but got the message: "[MMMM 1.ck]: HidIn: couldn't open joystick 0... ". Other device numbers yielded similar results. I searched and searched the archive of this list going back five years but did not notice any subjects with Space Navigator in them, and the wiki and forum search yielded nothing. How do I get my Space Navigator to work with ChucK? Les

introduce myself
by Carlo Ascani 21 May '12

Hi all, I am Carlo, from Italy. I would like to start studying a programming language for musical live coding purposes. I am using Linux. I was looking at ChucK and Supercollider. My question is: Is it possible to use Vim to perform live coding with Chuck ? Cheers, -- Carlo Ascani | www.carloratm.it skype: carloratm

using miniAudicle UI with another text editor
by henrique matias 07 May '12

07 May '12

Is there a way of "sending chuck code" to miniAudicle, therefore being able to use the GUI system ? I really like miniAudicle but i miss many "text-editor" features, like un/tabbing block of code, fast lauching / browsing files, etcs.. thanks chuckers!

coordinating rhythmic timing with unpredictable OSC events
by [chriswicks] 04 May '12

04 May '12

Hello all! I'm quite new to ChucK, and I have a question concerning rhythmic timing. I've got a program that I'm working on that accepts OSC events being sent from a C++ application. Now, the program chugs along, it's quite rhytmic, and I'd like to trigger melodic shreds based on values sent through OSC. No problem doing that. My problem comes from the fact that the C++ app isn't in sync with the ChucK VM, so the times at which it chooses to send data are pretty much never in sync with everything else that's going on, so the melodic shred is triggered but is not lined up rhythmically with everything else that's going on. Is there any way to hack it so that it waits to add the shred until it's lined up with everything else (quantized, so to speak). I'm not sure if I'm properly expressing the problem, so let me know if there's some way I can further clarify. Thanks very much! -crwicks
