Chapter 6. Connecting External Devices
Connecting MIDI Devices
By connecting an external MIDI device and exchanging
performance data, you can control the performances on one
device from the other. For instance, you can output sound
from the other instrument or switch tones on the other
instrument.

What’s MIDI?
MIDI stands for Musical Instrument Digital Interface, an
international standard which allows performance
information to be communicated among electronic musical
instruments and computers.
The HP103 provides MIDI connectors, which allow
performance data to be exchanged with external devices.
When these connectors are used to connect the HP103 to
external devices, an even wider range of possibilities
becomes available.
*A separate publication titled “MIDI Implementation” is also
available. It provides complete details concerning the way
MIDI has been implemented on this unit. If you should require
this publication (such as when you intend to carry out byte-
level programming), please contact the nearest Roland Service
Center or authorized Roland distributor.
Connection Examples
* To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power
on all devices before making any connections.

* Set Local Off if you have connected the HP103 to a MIDI
sequencer. Refer to “Switching Local Control on and Off” (p.
41). Also set your MIDI sequencer to MIDI Thru mode (so
that messages received at MIDI IN will be re-transmitted
without change from MIDI OUT). For details, refer to the
owner’s manual of your MIDI sequencer.
