and I've been pulling too many all nighters.
So I'm working on this clip from an old piano recital.  Wanted to add a composite envelope.  Added a velocity instead.  Bottom line... she's playing Bartok.. and all of a sudden VANISHES from the piano.   Music still playing and all.  Had to shake my head a couple of times and figure out what happened.
LOL
(well...it was funny to me anyway)
