SuperCollider CLASSES


Returns time since last triggered.
Inherits from: UGen : AbstractFunction : Object


When triggered, Timer measures the time (in seconds) elapsed since the previous trigger, and outputs this time value as a constant. Its output will not change until the next trigger. The initial value is 0.

If you need the time since the last trigger, where the time is continually updated, see Sweep.
