;; (demand trig reset ugens)
;; demand results from demand rate ugens.
;; When there is a trigger at the trig input, a value is demanded from
;; 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. 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.
