;; TRIGGER - sums instances of beh which are launched when input becomes
;; positive (> 0). New in 2021: input is resampled to *sound-srate*.
;; As before, beh sample rates must match, so now they must also be
;; *sound-srate*. This implementation uses eval-seq-behavior to create
;; a more helpful stack trace for SAL.
