InstrSpawner
Extension
ExtensionDescription
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)Class Methods
.latency
.new
Arguments:
| func | |
| args |
as per Patch, nil args will be auto-created. args that are Players will play continously in their own synths and be patched into each spawn event synth. args that are of rate \stream (all Pattern classes are rate 'stream') will be converted to an actual stream using .asStream and then iterated. args that are of rate \scalar (floats, Envs, samples) will be passed into the instr function and are subsequently fixed. |
| deltaPattern |
a float or pattern that returns floats. in seconds see InstrGateSpawner for time measured in beats and for variable legato |

Examples
xxxxxxxxxx// pchRatio will not stream, is fixed at -1(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), -1, Env.sine(0.2,0.4)],0.125).play)the Patch in the width input plays continuously and is patched into each spawn event
xxxxxxxxxx( 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
xxxxxxxxxx( 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
xxxxxxxxxx(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.
