public class PoissonTrigger
extends SynthCircuit

Generate triggers with a Poisson distribution. Triggers are generated by comparing WhiteNoise output with a threshold. The lower the threshold, the more frequent the triggers.

Port "probability" controls the probability of a pulse happening on any given sample frame. The average rate of the pulses is:

    averageRate = (probability / Synth.getFrameRate())
