The MIDI Messages of the EL-900
The MIDI messages can be divided into two groups: the Channel Messages
and System Messages. Below is an explanation of the various types of MIDI
messages which the EL-900 can receive/transmit.

Channel Messages

The Channel Messages are the data related to the performance on the keyboard
for the specific channel. Each time you play the keyboard on the EL-900, the
channel messages, which keys are played and how hard the keys are pressed,
will be transmitted via a specific channel. The channel messages from an
external keyboard can be received by the EL-900 and thus you can play the
EL-900 from an external keyboard.
Note On
Indicates which keys are played with the note numbers 0 through
127. The reception note range is C-2 (0) ﾐ G8 (127), C3 = 60.
Velocity
Indicates how hard the key is held. The range is 1 ﾐ 127.
Note Off
Generated when a key is released.

Program Change

The Program Change messages allow you to change voices in the middle of a
song. With these messages you can change the registrations of the EL-900.

Control Change

The Control Change messages let you select a voice bank, control volume,
panning, modulation, portamento time, brightness and various other controller
parameters, through specific Control Change numbers which correspond to
each of the various parameters.
