MiD! channels behave the same
way.
A
MIDI instrument transmits MIDI messages
to
the
receiving instrument when the
MIDI channel number of both units is the same. If the
MIDI
channels
are set as
follows, only sound
module B will sound when playing the keyboard.

MIDI Messages
There are various kinds of MIDI messages
that represent performance
information. MIDI
messages are divided into two
main types; messages transmitted on
a
MIDI channel
{Channel Messages) and
messages transmitted
regardless
of the
channel (System
Messages).
The following
describes which MIDI
messages apply
to the CR-80.
Q
Channel Messages
(messages transmitted
separately
on
a
MIDI
channel)
Channel messages transmit
perfomiance
controlling
information. Normally, these mes-
sages
cover almost all the controls.
How each
MIDI message controls the
performance is
determined by the settings on the
sound module unit.
Note Messages
This is performance
information of
rhythm patterns {equivalent
to keyboard
performance
information). Note messages
include the
following:
Rhyttim Machine Keyboard
Note Number

a
percussion sound
to
be played
Number that represents the
position on the key
Note On

percussion sound Press a Key
Note Off

Note numbers
{0
127)
represent the
notes on a keyboard, with number
60
corresponding
to Middle
C (
C4
).
Generally speaking, Note numbers
are
used
to distinguish pitches. On
a
rhythm machine
{or rhythm sound
module), however, Note
numbers
are used to
distinguish the percussion
sounds.
*
On
the
CR-60, a
specific Note
Number is assigned to eact^ percussion sound.
