demand results from demand rate ugens
|
|
|
|
A value is demanded from each ugen in the list and output 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.
|
|
|
|
duration: time values. Can be a demand ugen or any signal. The
|
|
next 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.
