Demand demand results from demand rate ugens

superclass: MultiOutUGen

Demand.ar(trig, reset, [..ugens..])

When there is a trigger at the trig input, a value is demanded each ugen in the list and output. The unit generators in the list should be 'demand' rate.

When there is a trigger at the reset input, the demand rate ugens in the list are reset.

trig - trigger. Can be any signal. A trigger happens when the signal changes from non-positive to positive.

reset - trigger. Resets the list of ugens when triggered.
