Description::
|
||
|
|
|
||
|
|
When a nonpositive to positive transition occurs at the input, Trig1
|
||
|
|
outputs 1 for the specified duration, otherwise outputs 0.

Trigger. Trigger can be any signal. A trigger happens when the
|
||
|
|
signal changes from non-positive to positive.
|
||
|
|
|
||
|
|
|
||
|
|
argument::dur
|
||
|
|
|
||
|
|
Duration of the trigger output.

Examples::
|
||
|
|
|
||
|
|
code::
|
||
|
|
|
||
|
|
{ Trig1.ar(Dust.ar(1), 0.2) * FSinOsc.ar(800, 0.5) }.play
|

This should sound like a continuous sine wave, although it is actually a series of 0.25 second synths.
