object PulseDivider extends Serializable
A UGen that decimates trigger by outputting one impulse each time a certain number of triggers at its input have been received.
Examples
// every two mouse-button clicks play { val in = MouseButton.kr(lag = 0) in.poll(in, "in") val out = PulseDivider.kr(in, 2, -1) out.poll(out, "out") () }
// rhythmic 1:4 pattern play { val p = Impulse.ar(8) val d = PulseDivider.ar(p, 4) val a = SinOsc.ar(1200) * Decay2.ar(p, 0.005, 0.1) * 0.3 val b = SinOsc.ar( 600) * Decay2.ar(d, 0.005, 0.5) * 0.3 Seq(a, b) }

def
ar(trig: GE, div: GE = 2, start: GE = 0): PulseDivider
- trig
a trigger occurs when the signal changes from non-positive to positive.
- div
decimation factor of the UGen. A value of 1 would cause an output trigger for each input trigger, whereas a value of 2 would cause an output trigger each time the internal counter has seen two input triggers.
- start
value of the internal counter. For example, if
div
is2
, then astart
value of0
(default) means that the first output trigger happens after two input triggers, astart
value of1
means that the first output trigger happens after just one input trigger. Negative values can increase the number of required input triggers for the first output trigger. For example, ifstart
is-1
, the first output trigger happens after three input triggers.
