USING MIDI

Your MD-1150 includes a feature called MIDI (Musical Instrument Digital Inter- face). MIDI is the universal standard for sending and receiving performance data between all types of electronic musical instruments, regardless of the manufac- turer.

Using MIDI, you can play music on your MD-1150 and another instrument at the same time while pressing the keys on only one, record your music to a se- quencer, acquire a wider selection of preset tones from a sound module, and much more.

Your MD-1150 has MIDI OUT and MIDI IN terminals.

ABOUT MIDI

Every MIDI-equipped instrument has MIDI OUT and IN terminals, and some also have a MIDI THRU terminal. Each of these terminals serves a different pur- pose.

MIDI OUT sends MIDI data to (“talks to”) the other MIDI instrument(s).

MIDI IN receives (“listens to”) MIDI data sent by the other MIDI instrument(s).

MIDI THRU lets you connect (“network”) additional MIDI instruments, and sends along to other MIDI devices a copy of all data it receives through its MIDI IN ter- minal.

The cable that connects MIDI devices does not actually carry sound between them, like a speaker wire carries sound from a receiver to a speaker. Instead, MIDI-equipped devices communicate with each other using digital codes (in- structions). One MIDI device sends digi- tal instructions representing exactly what is being played on it. The other MIDI device receives and translates those instructions, then produces (or records) the sound exactly as it was played on the first device.

MAKING THE MIDI

CONNECTIONS

To connect your MD-1150 to another MIDI-equipped device, you must use a MIDI cable, available at your local Ra- dioShack store.
