Description

A class to facilitate rendering of self-freeing SynthDefs (I.e., "grains"). It is possible to render the current setting to disk in various formats, e,g, to use the sounds in (hardware) drum samplers.

NOTE: The Synthdef needs to have the following features for this class to work properly:

free itself after a time set with a synth parameter called either sustain or duration
output channels need to be set to start with 0 and be the same as numChans

NOTE: This class was tested on osx only but should work on other platforms, too.

Simple example:( GrainRenderer( SynthDef(\bd, {|out = 0, freq = 67, sustain = 0.5, attack = 0.01, amp=0.1, startFreq = 1000| var osc = SinOsc.ar(XLine.kr(startFreq, freq, attack), 0.5pi); var env = EnvGen.kr(Env.perc(attack, sustain), doneAction: 2) * amp; Out.ar(out, osc * env!2); }).metadata_(( // parsed for slider ranges 'specs': ( out: [0,1,\lin, 1].asSpec, attack: [0,1,\lin, 0, 0.01].asSpec, sustain: [0,1,\lin, 0, 1].asSpec, startFreq: [100,1000,\exp, 0, 100].asSpec, freq:[10,100,\exp, 0, 67].asSpec, amp: [0,1,\lin, 0, 1].asSpec ))), numChans: 2, path: "~/Desktop".standardizePath, author: "say my name" ).edit )
