The Apple MIDI Interface has one Output and one
Input port. However, with these ports the interface
can communicate with 16 differerent MIDI channels,
which is the standard established by the MIDI
Developers Association.
All 16 channels can be used by one MIDI device,
such as a keyboard synthesizer, or the channels
can be split up among several different MIDI devices.
You could even have 16 different devices each
playing one part of a song, each part being received
on 1 channel. A common practice is for channel
10 to go to the device that is going to play the
drum parts and then the other 15 channels are
used to go to other MIDI devices. One MIDI device
might play the Piano sounds while another one
might have thatawesome bass sound that you gotta
have.
The Apple MIDI Interface only has one Input so
it can only accept input from one MIDI device
at a time. To receive input from two sources at
the same time using the Apple MIDI Interface,
you would need to add a MIDI merge box (from a
third-party developer).
