MIDI CHANNEL
A “MIDI Channel” is the avenue along which MIDI information is sent and received.
It is similar in principle to television channels. Up to 16 MIDI Channels can be sent or
received.
In order for MIDI communication to take place, the transmitting and receiving instru-
ments must be set to the same channel - for instance, if one instrument is sending out
MIDI data on MIDI Channel 1, the receiving instrument must also be set to MIDI
Channel 1.

NOTE Data
MIDI Note data is made up of four components: Note Number (the specifi c key or pitch
to play), Note On (telling the note to start playing), Note Velocity (the loudness of the
note) and Note Off (telling the note to stop playing).

PROGRAM CHANGE
MIDI uses “Program Numbers” to tell the receiving instrument what sound or tone to
play.
SWELL and GREAT CHANNEL:
Uses Program Numbers to select diff erent Preset Keys.
EXTERNAL ZONE CHANNEL:
Switches the program of the External MIDI equipment.

CONTROL CHANGE
“Control Numbers” are used to control devices such as an Expression Pedal, Foot Switch,
etc.
SYSTEM MESSAGE

SYSTEM EXCLUSIVE MESSAGE
Th ese messages are for sending and receiving characteristic data between the same model
or products made by the same manufacturer.
On this organ, the MEMORY DUMP feature can be used to send and receive all current
settings. In this way, you can record song data to an external MIDI sequencer along with
registration data so that the song will play correctly.
