Loading Chugins
by Perry Cook 03 Dec '17

Ok, another stab might be to build the chugin from source, to make sure the binary is the right DNA for your platform. These should be in a git somewhere. Sorry this is being such a pain.

I don’t have your environment, but some directory should do the trick. On my Mac, it’s in /usr/lib/chuck For now, you could try loading the specific ChuGin by name at runtime: chuck -chugin:<name> yourchuckfiles.ck I put the chugin I want right in the same directory just to make sure. Hope this helps. If it does, then you can probably work backward to finding the right directory to stash them.

How do I load ChuGins?
by Daniel Meowington 28 Nov '17

28 Nov '17

I'm on arch linux. Chuck and miniAudicle version 1.3.5.2. I installed the entire collection from git. Trying in miniAudicle to use `GVerb` or any other ChuGin for that matter outputs the message "undefined type 'GVerb'...". I also tried the command line by setting chugin-load to auto, setting the path, doing `chugin:GVerb`, none of which worked, all give the same message. I doubled checked and they are indeed in my /usr/local/lib/chuck folder.

Can I use ADSR UGen to envelope parameters other than gain (e.g. pitch)?
by Jean Menezes da Rocha 01 Nov '17

01 Nov '17

Hello, the ADSR UGen, to me, seems to have effect only over amplitude (which is its original function, I concede). However, is there any use case where I can use ADSR to map, say, pitch instead of amplitude, in order to avoid recurring to functions and for loops? Thanks in advance! -- Jean Menezes da Rocha Compositor Professor Doutorando em Música pela Universidade Federal da Bahia

DSP question: accumulating frequency info using FFT?
by Jascha Narveson 15 Oct '17

15 Oct '17

Chuck list! Help! I have the following idea and I’d like to hear what it sounds like: - play a sound into an FFT - as the FFT runs, for each bin: - - look at the magnitude info - - take a small fraction of this info and store it in a running total - - let the phase pass through unchanged - use the spectral data in the running total for the IFFT What I was hoping for was a slow emerging smear of all the frequencies from the input sound, kind of like a weird version of some kind of “infinite sustain” reverb. What I’m getting is the attacks of the original sound coming through, although fading in, and covered with noise. I think I’m doing something wrong by not doing something with the phase, but I’m not sure what. I’d love some advice… cheers, j - - - - c o d e e x a m p l e - - - - SinOsc synth => FFT fft => blackhole; UAnaBlob blob; IFFT ifft => dac; synth.freq(440); synth.gain(0.1); // set parameters 2048 => fft.size; // place to hold the FFT data as it comes in complex spec[fft.size()/2]; // place to store the accumulated FFT data, preload with zeroes complex acc[fft.size()/2]; for(0 => int i; i < acc.cap(); i++) { #(0, 0) => acc[i]; } // do it! spork ~ sawTune(); spork ~ accumulateFrequenciesViaFFT(); while (true) { 1::second => now; } fun void accumulateFrequenciesViaFFT() { while( true ) { fft.upchuck() @=> blob; // get the data blob.cvals() @=> spec; // for every bin... for(0 => int i; i < spec.cap(); i++) { // get the mag/phase for each bin by converting to polar spec[i] $ polar => polar newBin; // and get our running totals from acc acc[i] $ polar => polar accBin; // scale the inocming mag and add it to acc newBin.mag * 0.001 +=> accBin.mag; // let phase pass through newBin.phase => accBin.phase; /*Math.random2f(0, TWO_PI) => accBin.phase;*/ // convert back to complex and put back in the acc array accBin $ complex => acc[i]; } ifft.transform(acc); fft.size()::samp => now; } } fun void sawTune() { while (true) { Math.random2(48, 72) => int midinote; Math.mtof(midinote) => synth.freq; 333::ms => now; } }

Chuck Racks
by Spencer Salazar 14 Oct '17

14 Oct '17

Greetings, I would like to announce the first official beta release of Chuck Racks: http://mtiid.calarts.edu/projects/software/chuck-racks/ ChucK Racks makes it possible to write and execute ChucK programs as VST/AudioUnit plugins. The ChucK Racks architecture supports the following features: - Process incoming audio in ChucK (i.e. Audio FX plugins) - Process MIDI events from the host in ChucK programs (MIDI FX plugins) - Write synthesis plugins in ChucK that run as regular synthesizer audio plugins in a host/DAW - Synchronize clock and beat-time between a host/session and ChucK - Generate new MIDI/OSC events from ChucK (e.g. writing MIDI/OSC sequencer plugins) - Automate variables in ChucK code using host automation lanes Chuck Racks was developed by Jordan Hochenbaum, Rodrigo Sena, and myself here at CalArts. Enjoy and please feel free to let us know of any feedback! Regards, Spencer -- Spencer Salazar, PhD Special Faculty Music Technology: Interaction, Intelligence, and Design California Institute of the Arts ssalazar(a)calarts.edu | +1 831.277.4654 https://spencersalazar.com
