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

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

further testing shows that it's not about the odd harmonics, from the 5th harmonic (6th partials) onwards, sometimes you get unwanted sidebands with odd harmonics, sometimes with even ones. I'm monitoring the output (DFT) with Baudline and I tried driving Gen10 at different frequencies. -- Electronic Musician, Creative Coder, QA Engineer https://vimeo.com/creativecodingsalerno http://mbuoninfante.tumblr.com/ https://github.com/mariobuoninfante https://bitbucket.org/mariobuoninfante/

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

Hi, I found out that Gen10 has an issue with dealing with odd harmonics (not fundamental). It's easy to repro simply taking the example code and using the following coefficients instead: g10.coefs( [0., 0., 0.5] ); - shows the issue g10.coefs( [0., 0.5, 0.] ); - doesn't show the issue Hooking ChucK up to a spectrum analyzer it's easy to see the difference. In case there are odd harmonics, there are a lot of unwanted partials/sidebands, instead of having only the components specified in .coefs(). Gen9 doesn't seem to have this issue.

Re: [chuck-users] Routing SndBuf (Skot)
by Perry Cook 19 Feb '19

19 Feb '19

I don’t remember SndBuf ever being multichannel. In fact, there is a SndBuf2 just for stereo. That UG can be chucked to dac for auto stereo, or allows access to .chan(#) for arbitrary routing. SndBuf mixes everything down to mono, and I fear there is no support for > 2 channels via SndBuf. If my statements above are true, then Someone could do us all a cool favor by making a SndBufN chug.

Hi, I think you should use SndBuf2 instead of SndBuf.

Routing stereo sound file to dac channels
by Scott Smallwood 18 Feb '19

18 Feb '19

Dear chuckians… This is bizarre… I was sure I have done this in the past, but it isn’t working and now I’m a bit flummoxed…. Any ideas here? PS: I’m trying to route channels 0 and 1 of a stereo .wav file to dac channels 2 and 3. Should be simple. So why doesn’t this work?? I realize that I could just spit it into mono files… but why? I thought SndBuf supported up to 8 channels. — SndBuf sb; //read in stereo sound file "snd/squeakies/bell_4.wav" => sb.read; //works - and routes channel 0 of sb to dac.chan(3) sb.chan(0) => dac.chan(2); //doesn't work - claims NullPointerException sb.chan(1) => dac.chan(3); 1::minute => now; —ss [ - ] Scott Smallwood <http://www.scott-smallwood.com/> - Associate Professor - University of Alberta [ - ]
