For MIDI to control several instruments, each playing a different part at the
same time, it uses different channels. There are 16 channels available, and
each one can transmit any number of notes to any number of instruments,
over the same MIDI cable. Each instrument only responds to notes and
commands sent on the channel to which it is “tuned”.
The MIDI messages that Mark-Pro TWOi S transmits and receives fall into
several categories, as outlined in the MIDI Implementation Chart on page 52.
This section explains the messages and their use.
When you play a key on the Mark-Pro TWOi S, it sends a MIDI message that says
a note has begun, what MIDI channel it's on, what note it is, and the velocity
with which the key was pressed. When you release a key, a similar message
is sent saying that a note has ended, on which channel, what note, and the
velocity with which the key was released.
Control Change is the largest category of MIDI messages. T h e Mark-Pro
TWOi S has an extensive controller implementation, to help you alter your
performances and sounds flexibly as you play or in your recorded
sequences.
The

discussion
elaborates
on
each
of
these
messages.
]The Mark-Pro TWOi S recognizes Mod Wheel messages, which affect the sound
of different programsin different ways. Controller 1 can be used by itself,
or if more subtle control is desired, controller 33 can be used with controller
1.
