Omni On/Off
When set to Omni On, the HP 237R will sound as a result of
received MIDI messages, no matter which channel the
messages arrive on.
When set to Omni Off, the HP 237R will recognize only the
messages that arrive on the MIDI channel that has been
selected, as explained under “Set the MIDI Channel.”

Omni On is automatically set when the power is switched on.
Hold down the [Piano 1] button, the [Piano

and press the “F4” note to turn the setting
On, or the “G4” note to turn the setting Off.

Set the MIDI Channel
MIDI features sixteen MIDI channels, numbered 1–16.
The connected devices must be set to use the same MIDI
channels, otherwise no sound will be produced.
- In a setup where you wish to play the HP 237R and also
have another MIDI-equipped instrument or sound
module play the same notes, you should first set the
channel used for reception on your external device to the
same channel that you have the HP 237R set to use for
transmission.
- If using another MIDI keyboard as a master instrument,
and you wish to have the HP 237R played by it, you
would need to set the channel used for reception on the
HP 237R to the same channel that the master keyboard
will be transmitting on.
- When wishing to have a sequencer play the HP 237R, you
need to set the channel used or reception on the HP 237R
to the same channel that the recorded MIDI data is set to
use.
When the HP 237R is turned on, Channel “1” is selected.
While holding down the [Piano 1], [Piano 2],
and [Harpsichord] buttons, press the
appropriate key (C2–D4) on the keyboard.
The MIDI transmit channel and receive channel will
switch to the number that corresponds to the note you
pressed.
