InstrSpawner

Extension

Description

a Pbind-like spawner that plays an Instr with streams supplied to its inputs.

One nice feature is that it is easy to supply kr or ar rate Patches to the inputs and this will be played continuously and patched into each event. See examples below.// start and pchRatio are streamed ( InstrSpawner({ arg sample,start=0,pchRatio=1.0,env; PlayBuf.ar( sample.numChannels, sample.bufnumIr, pchRatio, 1, start * sample.bufFramesIr, 1 ) * EnvGen.kr(env,doneAction: 2) },[ Sample("a11wlk01.wav"), Pbrown(0,1,0.1,inf), Prand( Array.fill(4,{ Pseries(rrand(-20,30),[2,-2].choose,rrand(5,20)) }),inf).midiratio, Env.sine(0.2,0.4) ],0.06).play )

Examples

the Patch in the width input plays continuously and is patched into each spawn event( InstrSpawner({ arg freq,rq,width,fenv,fenvmod,envperc; width.debug("width"); // an OutputProxy RLPF.ar( Pulse.ar( freq, width ), EnvGen.kr(fenv,levelScale: fenvmod), rq) * EnvGen.kr(envperc, 1.0,0.3,doneAction: 2) },[ Pfunc({ 15.rand.degreeToKey([ 0, 2, 3, 5, 7, 8, 10 ]).midicps * 3 }), 0.1, Patch({ FSinOsc.kr(0.05).range(0.01,0.99) }), Env.asr, 6000, Env.perc(releaseTime: 0.8) ],0.125).play )

note: for beats see InstrGateSpawner

the stereo Patch in the width input causes the InstrSpawner to expand to stereo( InstrSpawner({ arg freq,rq,width,fenv,fenvmod,envperc; width.debug("width"); // an OutputProxy RLPF.ar( Pulse.ar( freq, width ), EnvGen.kr(fenv,levelScale: fenvmod), rq) * EnvGen.kr(envperc, 1.0,0.3,doneAction: 2) },[ Pfunc({ 15.rand.degreeToKey([ 0, 2, 3, 5, 7, 8, 10 ]).midicps * 3 }), 0.1, Patch({ [ FSinOsc.kr(0.05,0.0).range(0.01,0.99), FSinOsc.kr(0.05,0.5).range(0.01,0.99), ] }), Env.asr, 6000, Env.perc(releaseTime: 0.8) ],0.125).play ) ( Instr(\InstrSpawner,{ arg freq=1000,amp=0.1,env; SinOsc.ar(freq,mul: amp) * EnvGen.kr(env,doneAction: 2) }); i = InstrSpawner(\InstrSpawner,[ Pbrown(45,90,3,inf).midicps, 0.1, Env.sine // does not get streamed ], 0.1 ); i.play )

sliders are polled on the gui( Instr(\InstrSpawner,{ arg freq=1000,amp=0.1,env; SinOsc.ar(freq,mul: amp) * EnvGen.kr(env,doneAction: 2) }); InstrSpawner(\InstrSpawner,[ nil, // accept a default KrNumberEditor nil, // accept a default KrNumberEditor Env.sine // does not get streamed ], NumberEditor(0.1,[0.05,1.0]) // polled each time ).gui ) // how to get eventCount like sc2 Spawn ( InstrSpawner({ arg eventCount=0, freq,rq,width,fenv,fenvmod,envperc; // do something with eventCount if you need it... RLPF.ar( Pulse.ar( freq, width ), EnvGen.kr(fenv,levelScale: fenvmod), rq) * EnvGen.kr(envperc, doneAction: 2) },[ Pseries(0,1,inf), // infinite counting //aeolian Pfunc({ 15.rand.degreeToKey([ 0, 2, 3, 5, 7, 8, 10 ]).midicps * 3 }), 0.1, Patch({ LFTri.kr(0.1,[0.0,0.5],0.5,0.5) }), Env.asr, 6000, Env.perc(releaseTime: 0.1) ],0.25).play )

this is more flexible, is only on when you need it, and lets you do wrapping or scaling of the event count all in the pattern domain.
