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

Chunity (ChucK for Unity): Release!
by Jack Atherton 29 Jul '22

29 Jul '22

Dear all, Hello! I'm happy to announce the initial official release of Chunity (ChucK for Unity)! http://chuck.stanford.edu/chunity/ http://u3d.as/1bvM Chunity is the integration of ChucK in Unity. (For those of you not familiar with the Unity game engine, Chunity gives you the ability to do realtime sound + music generation natively in Unity, tightly coupled to interactions with graphical objects.) You can use most (possibly all?) ChucK features, run new ChucK code on-the-fly at any time, and communicate between Unity and ChucK using "global" (new keyword!) ints, floats, strings, Events, and 1D int and float arrays. (More types to come!) You can even run multiple VMs that share the same strong timing! Check out this video of things people have already made with Chunity: https://vimeo.com/263613454 And check out the original description of Chunity in this NIME paper: http://chuck.stanford.edu/chunity/files/2018-nime-chunity.pdf We want to know what you all do with this! Please feel free to send works in progress, bug reports, feature requests, finished works, etc. to the chuck-users mailing list! We are also planning to send a sparse series of follow-up emails covering tutorials, new features, and cool projects that people in the community have created. Please see the tutorials, documentation, etc. at the official Chunity website: http://chuck.stanford.edu/chunity/ Thank you and happy ChucKing!! Best, Jack + the ChucK team Music:Computing:Design @ CCRMA

Re: [chuck-users] Multichannel Mono Output using ChucK (Matthew.Noone)
by Perry Cook 30 Jan '20

The trick here is you also have to tell ChucK to be 4 channels. From the command line: chuck -c8 YourFile.ck depending on what your —probe shows, you might even have to specify which dac (and adc) to use, especially if they’re different device numbers or channel numbers. Also, might need to up the buffer size to avoid clicking, especially for lots of channels. Examp: chuck -c8 -bufsize2048 -in2 --dac1 --adc0 YourFile.ck Hope this helps, PRC PS: If you’re using MiniAudicle, then you need to do some menu stuff to pick output/input devices, and numchannels as well. > On Jan 30, 2020, at 8:02 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.

Classes to effectively use FluidSynth microtonally in ChucK
by Forrest Cahoon 30 Jan '20

30 Jan '20

Some time ago, I extended the FluidSynth chugin with hooks into libfluidsynth's tuning API. Once I started working with some more sophisticated soundfonts (such as those at https://sites.google.com/site/soundfonts4u/) I found a problem: it turns out that, the way libfluidsynth tuning works, the sample for the assigned-to note number is retuned to the pitch to which it is assigned, instead of using a sample which meant to be close to the desired pitch. So I wrote a set of ChucK classes so that I could just specify the note I want and let ChucK decide which MIDI note number to assign it to. If this is possibly of interest to you, check out my code at https://github.com/forrcaho/ChucK-code/tree/master/fluidsynth .

Hi all, I am trying to get multichannel output (to four speakers) using ChucK. I'm running on a Mac and using a Scarlett 18i8. I've tried running this test code. SinOsc s0 => dac.chan(0); SinOsc s1 => dac.chan(1); SinOsc s2 => dac.chan(2); SinOsc s3 => dac.chan(3); 3::second => now; But I get this error. chuck](VM): NullPointerException: (UGen link) on line[3] in shred[id=1:MULTI] Any ideas?

Re: [chuck-users] Float to Int
by Perry Cook 21 Jan '20

We also added Std.ftoi(x) to the language a while back (at 1.3.2.0). It’s much clearer to read, and more obvious as to what’s going on and why, than the casting notation. To round, just add 0.5 to x in the function arg. so: > Std.ftoi(0.4*myBuf.samples()+0.5) => myBuf.pos; would set your play pointer to the 40% point in the sound buffer. Prc Sent from my iPhone > 1.

Conversion float to int using SndBuf
by Mícheál Ó Catháin 21 Jan '20

21 Jan '20

Hi What is the best way to convert a float to int in the following please? //I want to set myBuf.pos to a percentage of myBuf.samples()... //Start playing at say 40% through the total number of samples. 40.0 => float pctPosInit; pctPosInit/100*myBuf.samples() => myBuf.pos; This throws the error argument types don't match. I'm not seeing how to convert the float to an int here. Thanks for your help! Micheal
