;; (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.
;; Play a little rhythm
