Connecting to MIDI Devices
Read this chapter if you wish to connect the HP 237R to an external MIDI device.
If the HP 237R is connected to a MIDI sequencer, such as one from the MT series, a performance recorded on the HP 237R can be transmitted to the MIDI sequencer. It is also possible to record the performance directly on the MIDI sequencer. The recorded performance can be saved on the MIDI sequencer.
When the HP 237R is connected to an MT series sequencer, the rich variety of sounds built into the MT series sequencer can be played from the keyboard of the HP 237R.
About MIDI
MIDI, short for “Musical Instrument Digital Interface,” was developed as a standard for the exchange of performance data between electronic instruments and computers.
The HP 237R is equipped with MIDI connectors to allow such exchange of performance data with external equipment and devices. Connecting the keyboard to other devices with these jacks provides you with an even greater variety of ways to use your keyboard.

MIDI In Connector
Use a MIDI cable (sold separately) to connect from here to the MIDI Out connector on the external MIDI device.
MIDI messages sent from connected external equipment will be received here. As a result, the HP 237R will produce sound, change tones, or perform other operations.
MIDI Out Connector
Use a MIDI cable (sold separately) to connect from here to the MIDI In connector on the external MIDI device. Performance data detailing what has been played on the keyboard, and other data, such as that generated when a pedal is depressed, is sent out from here to external MIDI devices.
