class:: InTrig
summary:: Generate a trigger anytime a bus is set.
categories:: UGens>InOut, UGens>Triggers
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.
classmethods::
method::kr
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;
