sc_trig — Timed trigger


Plugin opcode in scugens.

Timed trigger. Port of Supercollider's Trig ugen


aout sc_trig ain, kdur
kout sc_trig kin, kdur


initialvalue If given, sets the internal state. Default=0


ain -- Trigger. Trigger can be any signal. A trigger happens when the signal changes from non-positive to positive.

kdur -- Duration of the trigger in seconds.

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.


Here is an example of the sc_trig opcode. It uses the file sc_trig.csd.

Example 880. Example of the sc_trig opcode.
