@title{(t-duty rate duration reset doneAction level gap)}
demand results as trigger from demand rate ugens.
A value is demanded each ugen in the list and output as a trigger
according to a stream of duration values. 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 and the duration are
reset. The reset input may also be a demand ugen, providing a
stream of reset times.
NOTE: sclang reorders the inputs to be 'duration reset level
doneAction', rsc does not.
duration - time values. Can be a demand ugen or any signal.
The next trigger value is acquired after the
duration provided by the last time value.
reset - trigger or reset time values. Resets the list of ugens
and the duration ugen when triggered. The reset input
may also be a demand ugen, providing a stream of reset
times.
doneAction - a doneAction that is evaluated when the duration
stream ends.
level - demand ugen providing the output values.
