Cautions when Connecting an External MIDI Device

Here we will explain the “Local On/Off” and “Omni On/ Off” settings that you need to be aware of when connecting the HP 237R to an external MIDI device.

■Disconnecting the HP 237R’s keyboard and internal sound generator–Local On/Off

When the HP 237R is connected to a MIDI sequencer or the like, set it to Local Off.

As shown in the diagram, the data that is produced when you play the keyboard will reach the sound generator by two routes, (1)and (2), causing each note to be played in duplicate. To prevent this, select the Local Off setting to cut route (1).

If the HP 237R is connected to a Roland MT series (except MT-80s), it is not necessary to make the Local Off setting. When the power is turned on, the MT series will transmit a Local Off message. If you turn the power on in the order of first the HP 237R and then the MT series, the HP 237R will automatically be set to Local Off.
