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.
