I read it as meaning activation by the note-off message.
That's what I would have expected, anyway.

So I see!  I didn't try to penetrate all that MIDI code too deeply,
but I have a feeling that quite a bit of stuff would need to be added.

ATM, it seems to me that a UDO is a better workaround. Here's a quickie that
seems to work:

opcode MidiNoteOff, k, ii
	ichan, ikey xin
	kstatus, kchan, kdata1, kdata2 midiin
	xout (kstatus == 128 && kchan == ichan && kdata1 == ikey)? kdata2 : -1
endop

It's a pity that 0 is a legal release velocity -- means having to check
for non-negative return.)
