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] Closing MIDI Ports (Mario asks)
by Mario Buoninfante 28 Mar '20

Hi Perry, Thanks for the suggestion, I'll try that out. In fact I realized that unfortunately killing the shred, or terminating the program is not enough to close the ports. You need to terminate ChucK. An alternative could be that of using Std.system("chuck midi_config.ck"). At this point I could simply print the port names on the terminal. Anyway, I'll try both and see.

I’m not sure if they can be closed, but as long as you don’t chuck them to now, the extra ones really shouldn’t take up (much) computational resources. One option would be to first run a MIDIConfig.ck file that opens them all and writes all the names and numbers into a MIDICONFIG.txt file. Then when you run your main file, it reads that and only opens the one(s) you need. Or your first MIDIConfig.ck file could pick the one(s) you need and write only them into the temp file. I’ve done this for PLOrk pieces, to figure out if laptops have accelerometers, and what orientation those are. prc from MyiPhone > On Mar 27, 2020, 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.

Closing MIDI ports
by mario buoninfante 26 Mar '20

26 Mar '20

Hi, Is it possible to close a MIDI port? I'm working on a MIDI class, and to print all the available ports, I open them one at the time and get the name. Then I end up with tons of open MIDI ports I'm not actually using. Apart from this, another user case could be a live set where different scripts are launched and each of them wants to talk to a specific MIDI port. Doing so one ends up with a lot of /leftovers/.

compiling miniAudicle on ubuntu 18.04
by Forrest Curo 25 Mar '20

The instructions for doing this when chucK 14 is already installed & working are basically unclear, ie changing some unnamed link from src in the miniAudicle directory to point to the directory containing chucK.

Re: [chuck-users] float to int

Also, A more obvious and Java-like way to convert float to int is the built-in function: Std.ftoi(myFloat) => int myInt; Sent from my iPhone > On Mar 10, 2020, at 8:51 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.

using global variables as arguments in sporking functions
by herman verbaeten 10 Mar '20

10 Mar '20

Hi, I'm having a problem passing a changing parameter(by an LFO in another function) to a function i'm sporking . Maybe this isn't possible :-( but i'd like your opinion) This is part of my script. Let me tell you this: When i give float Cfreq an initial value of 0.3 LFO does change gain of SinOsc c. If i don't give it an initial value and have LFOtochangeCfreq change it -> no sound. SinOsc m => SinOsc c => Pan2 p => dac; 2 => c.sync; float Cfreq; //if i replace this line by: .3 => float Cfreq; spork ~ LFOtochangeCfreq(.1); spork ~ LFO(Cfreq); fun void LFOtochangeCfreq(float variation) { SinOsc lfo => blackhole; variation => lfo.freq; while( true ) { 1000::samp => now; <<<lfo.last() => Cfreq>>>; } } fun void LFO(float LFOfreq) { SinOsc lfo => blackhole; LFOfreq => lfo.freq; while( true ) { 1::samp => now; lfo.last() => c.gain ; } } while (1) 10::ms=> now;

Vec3 interpolation interpolate.ck
by herman verbaeten 07 Mar '20

Hi, In the examples included in the miniaudicle installation there is a "interpolate.ck" But i cant't find any documentation about this. It uses vec3. I'd like to know more about how to use i.update and i.interp. Thanks ! Kind regards, Herman // name: interpolate.ck // desc: using vec3 as an non-linear, slewing interpolator // this is quite useful to making a percentage progress // towards a goal, in an amount proportional to the slew // and some delta time // connect SinOsc foo => dac; // the interpolator vec3 i; // the interpolation rate 10::ms => dur irate; // set initial .value, .goal, .slew i.set( 440, 440, .05 * (second/irate) ); // spork interpolate function spork ~ interpolate( irate ); // main shred sets the goal while( true ) { // set interpolator goal i.update( Math.random2f(200,1000) ); // every so often 500::ms => now; } // function to drive interpolator(s) concurrently fun void interpolate( dur delta ) { while( true ) { // interpolate (can also get new value via .value) i.interp( delta ) => foo.freq; // advance time by rate delta => now; } }

Hi, I was hoping to use an ADSR as a pichenvelope But Chuck doesn't want to accept it. Is there another way to achieve this? SndBuf buf => dac; ADSR Penv => buf.rate; Kind regards, herman
