In classic granular synthesis the grains are triggered by a uniform random number generator or white noise. In these examples, I took a CloudBank? and triggered it with a PulseTrain? in order to achieve a regular pulse controllable by a !BPM fader. Then I added some noise (scaled by a !Jitter parameter) so you could gradually make the grain attacks less regular and more random. There are also examples of using an InputOutputCharacteristic? as a sieve on the FrequencyJitter?. By varying the smoothness of the InputOutputCharacteristic?, you can reject any random pitches that don't fall within a particular scale (and as you increase the smoothness parameter, allow more pitches through the sieve until you are back to a random jitter again).

In the second example, Density is controlled by a bpm:dutyCycle: expression. By controlling the duty cycle of the metronome, you control whether the grain cloud has a density of 0 or a density controlled by the !Density controller.
