You need some edge if you ever want to re-use a VVID.

OK Riddle me this
* I press key #60 on my keyboard:
t0: VVID(60).cutoff = 0.7
t0: VVID(60).velocity = 64
t0: VVID(60).pitch = 60.0
t0: activate VVID(60)
-- VVID(60) is playing
t1: deactivate VVID(60)
-- VVID(60) goes into release stage (I have a long envelope release)
* I press key #60 on my keyboard again:
t0: VVID(60).cutoff = 0.1
-- What happens?
Did I just ask for the cutoff to change on the tail of the first note, or
did I ask it to start thinking about a new note? You've got an ambiguity
in the dialect. Forcing an allocate edge clarifies the exact intentions.
