Workshop on Audio Plug-Ins Design in Faust
by Romain Michon 19 Feb '14

19 Feb '14

Hi Folks, I'll be giving a workshop on Audio Plug-Ins Design in Faust this summer at the Center for Computer Research in Music and Acoustics (Stanford University, USA) this summer (Mon, 07/07/2014 - Fri, 07/11/2014). Thanks to Spencer Salazar, Faust can be used to easily create chugins so I thought that this event might interest some of the members of this list. More informations are available on this page: https://ccrma.stanford.edu/workshops/faust-workshop-2014 You can also contact me directly if you have specific questions: rmichon(a)ccrma.stanford.edu Cheers, -- Romain Michon PhD Candidate Center for Computer Research in Music and Acoustics Stanford Universityhttp://ccrma.stanford.edu/~rmichon

I am interested in using chuck as an embedded language? I want to try to model circuit with transfer functions.

Command line arguments
by Stuart McDonald 12 Feb '14

12 Feb '14

I am entertaining an aspiration to send an arbitrary list of wav files to chuck to process, so that a user could drag and drop files into a directory, and wrap a call to chuck in a script that takes the result of ls and passes the files to chuck as command line arguments. The closest I've found on Google is this post: https://lists.cs.princeton.edu/pipermail/chuck-users/2011-January/005932.ht… much changed since then? It's not essential as I could contrive the calling script to compile a .ck file containing the wav files ahead of time and pass that to chuck, but I figured I'd check in case there are more seemly options. Thanks Stuart

Re: [chuck-users] machine.add issues (Amy Crawford)

Amy, Judging from the C: in your post, I gather you are using Windows? If so, we had a bug with ChucK wherein it was interpreting the colon as the usual marker for arguments to a program. So it was interpreting that path as a ChucK file named "C" with an argument of all the path after the colon. Spencer made a patch for that and released it as an update. Now ChucK ignores a colon so early (meaning that we can't have single letter ChucK files, but that would be pretty goofy anyway). Make sure you have the newest version of ChucK from the download site: http://chuck.stanford.edu/release/files/exe/chuck-1.3.3.0.msi You may have to remove previous versions to do a clean install.

new to chuck having machine.add issues
by Amy Crawford 11 Feb '14

11 Feb '14

Hi there! I took the coursera course for chuck programming and all was going well until I go to use machine.add() to make my score and all instruments concurrent. for some reason it reads [C]: no such file or directory I added my files to another computer and the same exact thing occurred. every time I add the shred and Any time I use Machine.add() in any other programs the same thing occurs even though i am using me.dir("/myfile.ck") I can't seem to make any of my files concurrent to one another because its not working. Any help is appreciated greatly!! Thanks! Amy

Listener
by Philipp Blume 07 Feb '14

07 Feb '14

I am looking to implement a listener into my (very simple) ChucK program. I want to operate a bank of virtual sliders that send their position to ChucK. In what program/application can I build such a slider, and where in the ChucK API can I read up on listeners? I don't yet know my way around the documentation, though I do have the Kapur, Cook, Salazar, & Wang text which is wonderful. Thanks in advance! Philipp Blume

Re: [chuck-users] Matrix of Impulse Generators

Yep, having that resource allocation and connection to the dac inside your infinite loop is the culprit. In fact, almost everything in that function is static initialization, so chould be moved outside the while(1) context. This fixes it for real: fun void iGen(int i1, int j1) { Euclid(i1,j1,a1,b1) + Euclid(i1,j1,a2,b2) => float dist; <<< dist >>>; SinOsc s => ADSR e => dac; e.set(35::ms, 8::ms, .1, 200::ms); Math.pow(0.65,(dist)) => s.gain; i1*x + j1*y => s.freq; while(true) { e.keyOn(); (440)::ms => now; e.keyOff(); (440*Math.pow(1.2,dist))::ms => now; } } ----- Original Message ----- 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..."

Thanks, Stefan! That did take care of my problem! I didn't even trigger a new note, I simply added the line e=<dac; at the end of my function iGen.
