Re: [chuck-users] Chugin for UI (oscilloscope)
by Perry R. Cook 15 Apr '20

15 Apr '20

Well, MAUI is a chugin, only for Mac, so there is precedent for UI in Chugin. MAUI is currently broken in the command line, only working in MiniAudicle. Perhaps Spencer/Ge can chime in on the vagaries of doing UI/graphics via Chugin??

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

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

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.

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; } }
