NPVoicerL | SuperCollider 3.14.0-dev Help

Description

A voicer that can limit the maximum number of playing voices. Also, it can handle voices with fixed-duration synths reasonably well.

Mainly code examples and tests for now:s.boot; s.latency = nil; // make an NPVoicer with an Ndef in it // prime it to play the \default synthdef ( g = NPVoicerL(Ndef(\piano)); g.prime(\default); g.hasGate; g.play; ) // play 4 notes in it, and post voiceHistory ( g.maxVoices = 4; g.put(36, [\freq, 36.midicps, \amp, 0.2]); g.postHist; g.put(46, [\freq, 46.midicps, \amp, 0.15]); g.postHist; g.put(55, [\freq, 55.midicps, \amp, 0.12]); g.postHist; g.put(63, [\freq, 63.midicps]); g.postHist; ) // try releasing a note g.release(46); g.postHist; g.releaseAll; g.postHist; // repeat notes individually // - the previous instance of that note goes away g.put(46, [\freq, 46.midicps, \amp, 0.15]);g.postHist; g.put(55, [\freq, 55.midicps, \amp, 0.12]);g.postHist; g.put(36, [\freq, 36.midicps, \amp, 0.2]);g.postHist; g.put(63, [\freq, 63.midicps]);g.postHist; // try the steal modes: g.stealMode = \oldest; g.checkLimit; g.postHist; g.put(74, [\freq, 74.midicps, \amp, 0.1]);g.postHist; g.stealMode = \lowest; g.checkLimit; g.postHist; g.put(38, [\freq, 38.midicps, \amp, 0.1]);g.postHist; g.stealMode = \softest; g.checkLimit; g.postHist; g.put(84, [\freq, 84.midicps, \amp, 0.05]);g.postHist; // test self-ending voices with fixed durations: // the NPVoicerL tries to find out when the note will end, // and removes it from the list and the proxy.
