This would stop every note of the channel receiving this control change

still should play because of the ADSR release time.

The question is what happens at the other end when a note gets struck a
second time.
a) Nothing, the note is already on.
b) Re-trigger, the voice is reset and the note gets played from the top
c) Trigger, a new voice is assigned and will play simultaneously to
previous voices
Hi,
I'm pretty sure I've seen this dealt with on the list before, but can't
find it.
With the program I'm fumbling around trying to create, it will be possible
for successive note on events for the same pitch to occur without note off
events intervening.
Does the MIDI spec allow such things?
Sorry to answer myself so soon...
I guess it is allowed. The simplest case being a sequencer outputting to
the same channel and port as a keyboard player. Nothing can prevent this -
right?
And
there's no way in the world that missing note-offs could be added in,
in a fashion guaranteed to cover all possible permutations of connections,
or without delaying the note-on which implies a missing note-off.
An all-notes-off will take care of any missing note-offs

The bash-script prototype of the program did
this, and, I believe, the
soft-synths used, acted appropriately - that is, re-triggered the notes.
So I guess the question is, does it make any difference if I add-in the
note-off events - which, thinking about it, is going to be tricky because,
basically, although the program is sequencing, it will be real time and is
not psychic!
Cheers,
James.
