After a quick test seems to work fine on my Crow.
One bug i noticed when using this on SOUND/TRANSIENT if you do send more than one note per channel (yes, i know this is designed as mono only) it will about half of the time freeze that current channel on that note until a new note arrives. This does not happen with SOUND/SUSTAIN.
Also pleased, that this seems to also work on SHAPE, which could be nice, to use all these channels as envelopes.
