internally, on the sound card, it wouldn't make a difference...if you have 2
midi instruments on these two channels, then you should play them on the
same channel (hence the same instrument).

Hi, thanks for your quick anwser.
So, if two tracks use the same channel, I should just play them both on
the
NotePlayer representing that channel, and not on 2 different NotePlayers?
Thanks,
Maarten

Hi again Maarten,
Therre's MIDI files type 0, 1 and 2 actually number 2 being an
asynchroneous
multi track format.
There's nothing in the standard that says you can't send the same note on
more than one track. In fact, each MIDI event is the event type and the
channel. so you could send 16 consecutive message on each channel without
a
problem.
In a typical scenario however, you have MIDI gear setup, one on each
channel
(track) atleast most software planned it that way, though some do allow
to
work differently. since it's very likely that you'd want to play the 16
notes with the same instrument. you would typically have the setup the
bank/programs each time you send a message to a given track since the
MIDI
gear connected to it would change setup each time you want a different
instrument to be played. So you could do it, but you be probably sending
much more information (messages) over the MIDI network to get the job
done
rather than when you setup one instrument / one track setup.
And since MIDI gear today is typilcally GM, GM2, Roland or Yamaha
compliant,
they are all extensions of the GM standard hence work the same way give
or
take manufacturer specific features like RPNs and NRPN which is all done
through sysex essentially.
Hope this helps clarify things.
