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

building miniAudicla on debian "cannot find -lqscintilla2"

Hi! I'm trying to build miniAudicle under debian but the build fails like this: /usr/bin/ld: cannot find -lqscintilla2 collect2: error: ld returned 1 exit status make[1]: *** [makefile.qt-alsa:270: miniAudicle] Error 1 make[1]: Leaving directory '/mnt/data/atte/medium/software/chuck/miniAudicle-1.3.5.2/src' make: [makefile:38: linux-alsa] Error 2 (ignored) If I try to install libqscintilla2-dev I get this: atte@pandrup:~/software/chuck/miniAudicle-1.3.5.2/src$ sudo apt-get install libqscintilla2-dev Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libqscintilla2-qt4-dev' instead of 'libqscintilla2-dev' libqscintilla2-qt4-dev is already the newest version (2.10.4+dfsg-2.1). Any pointers appreciated. -- Atte http://latestyoutube.a773.dk | http://a773.dk

Re: [chuck-users] MidiIn/MidiMsg expansion
by Mario Buoninfante 20 Jan '21

Hi, I suppose one solution could be to have a new dedicate class (ie SysexMsg) with a getSysex() method, and then tweak the various bits that deal with receiving MIDI so that if the incoming msg is a sysex we can use a SysexMsg object instead of a MidiMsg one. The end result could be something along this line: MidiIn min; MidiMsg msg; SysexMsg sysex; ... ... while (true) { min => now; while (min.recv(sysex)) do something while (min.recv(msg) do something else } cheers, Mario

MidiIn/MidiMsg expansion
by Mario Buoninfante 20 Jan '21

20 Jan '21

Hi all, As you know I was trying to add sysex support to ChucK, and there are some progress there. I managed to let sysex msg through, and I can get the first 3 bytes using the data1, data2 and data3 member variables (MidiMsg). But of course sysex messages can have any length, so I was trying to find a way to return an array containing the received sysex. It's easy enough to internally store the sysex message received (ie tweaking the MIDI callback and MidiIn and increasing the array used to store incoming MIDI msg), but then when it's time to retrieve this array, well I'm a bit lost tbh. MidiMsg in midiio_rtmidi.cpp appears to be a union, and this makes things a bit trickier since I was thinking about having a member method that returns the sysex array (ie similar to SerialIO.getytes()). Does anyone have any idea about the best way to proceed here? Any help is really appreciated :) cheers, Mario

Try out this VST instrument/effect chugin
by David Braun 11 Jan '21

11 Jan '21

I created a chugin for Windows that does VST effects and instruments all in one. https://github.com/ccrma/chugins/pull/47 Sample code: VST vst => dac; vst.loadPlugin("C:/VSTPlugIns/Serum_x64.dll"); <<< "num parameters: ", vst.getNumParameters() >>>; <<< "parameter 0 is named: ", vst.getParameterName(0) >>>; vst.loadPreset("serum_preset.fxp"); vst.setParameter(0, vst.getParameter(0)); while(true) { vst.noteOn(60, 1.); 200::ms => now; vst.noteOff(60, 0.); 250::ms => now; } Please checkout the branch (literally) and try it out!

Does a Std.system call block concurrency?
by federico lopez 01 Jan '21

01 Jan '21

Hi, Is the ChucK thread disrupted by the execution time of a Std.system script call? In the code below, sporking a fast script, e.g. Std.system("sleep 0"), there is no noticeable disruption, but sporking a time consuming version e.g. Std.system("sleep 3") there is a disruption in the other sporks. I'm trying to call R scripts using ChucK concurrency. // test code, run with --caution-to-the-wind command-line flag Noise n => Envelope e => dac; fun void metro() { while(true) { e.keyOn(); 10::ms => now; e.keyOff(); 990::ms => now; <<< now, "samples" >>>; } } fun void callSystem() { while(true) { Std.system("sleep 0"); // comment this to test //Std.system("sleep 3"); // uncomment this to test 1000::ms => now; } } spork~ metro(); spork~ callSystem(); while(true){10::ms => now;} // end test code
