■ NOTE ON/OFF
This message sends data when a key is pressed (NOTE ON) or released (NOTE OFF).
A NOTE ON/OFF message include a note number (to indicate note whose key is
being pressed or released) and velocity (keyboard pressure as a value from 1 to 127).
NOTE ON velocity is always used to determine the relative volume of the note. This
keyboard does not receive NOTE OFF velocity data.
Whenever you press or release a key on this keyboard, the corresponding NOTE ON
or NOTE OFF message is sent by constant velocity from the MIDI OUT terminal.
■ PROGRAM CHANGE
This is the tone selection message. PROGRAM CHANGE can contain tone data
within the range of 0 to 127.
A PROGRAM CHANGE message (0 to 99) is sent out through this keyboard’s MIDI
OUT terminal whenever you manually change its tone number. Receipt of a PRO-
GRAM CHANGE message from an external machine changes the tone setting of this
keyboard.
This keyboard can send tone data within the range of 00 to 99 and receive tone data
within the range of 0 to 127*.
* When GM mapping is turned on. When turned off, tone data is received in the
range of 0 to 99.
Note
• Channel 10 is for the drum part only, and it does not receive Program Change
messages. When receiving MIDI data, it sounds percussion sounds produced by this
keyboard.

This message carries pitch bend information for smoothly sliding the pitch upwards
or downwards during keyboard play. This keyboard does not send pitch bend data,
but is can receive such data.
■ CONTROL CHANGE

keyboard play. CONTROL CHANGE data includes a control number (to identify the
effect type) and a control value (to specify the on/off status and depth of the effect).
