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.
