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

ChucK code search, an experiment!
by Tom Lieber 27 Oct '12

27 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

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 23 Oct '12

23 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

nice thread about FM synthesis using chuck/supercollider

odd Hid behavior maybe just on OS 10.7
by Jeff Albert 09 Oct '12

09 Oct '12

Hi all, We are doing a piece in our laptop orch that uses Hid input from the keyboard and mouse. The group does not have matching machines. All but 1 are Macs, with the OS ranging from 10.6.x to 10.8.2. The code (pasted below) works on the windows machine and the 10.6 and 10.8 Macs, but not on any of the machines running OS 10.7.4.

Of course you are, that's a virtue for programmers. Quite often the way to lazyness is through understanding. Well, the way to lazyness you can get away with is. Being lazy, making sweeping generalisations, theft, all great stuff ;-) Yours, Kas.
