Description::
|
||
|
|
|
||
|
|
Any time the bus is "touched", ie. has its value set (using "/c_set"
|
||
|
|
etc.), a single impulse trigger will be generated. Its amplitude is the
|
||
|
|
value that the bus was set to.
|
||
|
|
|
||
|
|
If the bus is set link::Classes/Bus#Synchronous Control Bus Methods#synchronously:: no trigger will be generated.

|
argument::bus
|
||
|
|
The index of the bus to read in from.
|
||
|
|
|
||
|
|
argument::numChannels
|
||
|
|
The number of channels (i.e. adjacent buses) to read in. You
|
||
|
|
cannot modulate this number by assigning it to an argument in a
|
||
|
|
SynthDef.

|
|
Examples::
|
||
|
|
|
||
|
|
code::
|
||
|
|
s = Server.local;
|
||
|
|
b = Bus.control(s,1);
|
||
|
|
|
||
|
|
SynthDef("help-InTrig",{arg out=0,busnum=0;
|
||
|
|
var inTrig;
|
||
|
|
inTrig = InTrig.kr( busnum );
|
||
|
|
Out.ar(out,
|
||
|
|
EnvGen.kr(Env.perc,gate: inTrig,levelScale: inTrig ) * SinOsc.ar
|
||
|
|
)
|
||
|
|
}).play(s,[\out, 0, \busnum, b.index]);
|
||
|
|
|
||
|
|
|
||
|
|
b.set(1.0);
|
||
|
|
|
||
|
|
b.value = 1.0;
|
||
|
|
|
||
|
|
b.value = 0.2;
|
||
|
|
|
||
|
|
b.value = 0.1;
