Trig timed trigger
Trig.ar(trig, dur)
When a nonpositive to positive transition occurs at the input, Trig outputs the level of the triggering input for the specified duration, otherwise it outputs zero.
trig - trigger. Trigger can be any signal. A trigger happens when the signal changes from non-positive to positive.
dur - duration of the trigger output.
