Connecting to MIDI Devices
Turning Transmission and
Reception of Control
Changes On/Off
Messages known as “Control Changes” are used to convey to
another device information about the instances where you
have pressed a pedal, or have turned On/Off the Chorus or
Reverb effects.
Each time the power is turned on, the instrument will always
be set to “On” (it will transmit/receive all Control Change
messages).
If you set it to “Off” the HP 237R will no longer send or
receive any Control Change messages.
While holding down the [Piano 1] button,
[Piano 2] button, and [Harpsichord] button,
press the “A5” note to turn the setting On,
or the “B5” note to turn the setting Off.
