MIDI MIDI, the Musical Instrument Digital Interface, is a world-standard communication interface that allows MIDI-compatible musical instruments and equipment to share musical information and control one another. This makes it possible to create "systems" of MIDI instruments and equipment that offer far greater versatility and control than is available with isolated instruments.

MIDI THRU OUT IN The MIDI IN connector receives MIDI data from an external MIDI device which can be used to control the PSR-1700 or PSR-2700. The MIDI THRU connector re-transmits data received at the MIDI IN connector, al- lowing "chaining" of several MIDI devices. The MIDI OUT connector transmits MIDI data generated by the PSR-1700 or PSR-2700 (e.g. note and velocity data produced by playing the keyboard). q Simple MIDI Control ... Tone Generator MIDI IN MIDI OUT PSR-1700/2700 MIDI Keyboard MIDI OUT Most MIDI keyboards transmit note and velocity (touch response) information via the MIDI OUT connector whenever a note is played on the keyboard. If the MIDI OUT connector is connected to the MIDI IN connector of a second keyboard (synthesizer, etc.) or a tone generator (essentially a synthesizer with no keyboard), the second keyboard or tone generator will respond precisely to notes played on the original transmitting keyboard. The result is that you can effectively play two instruments at once, providing thick multi-instrument sounds. The PSR-1700 and PSR-2700 also transmit "program change" data when one of its voices is selected. Depending on how the receiving device is set up, the corresponding voice will be automatically selected on the receiving keyboard or tone generator whenever a voice is selected on the PSR-1700 or PSR-2700. MIDI IN PSR-1700/2700 The PSR-1700 and PSR-2700 are capable of receiving the same MIDI data, so a second MIDI keyboard connected to the PSR-1700 or PSR-2700 MIDI IN connector can be used to remotely play the instrument and select voices as required. q MIDI Sequence Recording ... Sequencer MIDI IN MIDI OUT PSR-1700/2700 Although the PSR-1700 and PSR-2700 feature a built-in "sequencer" (the Song Memory is a type of sequencer), the same type of musical information transfer described above can be used for more sophisticated MIDI sequence recording using an external sequencer or music computer. A MIDI sequence recorder or music computer can be used to "record" MIDI data received from a PSR-1700 or PSR-2700, for example. When the recorded data is played back, the PSR-1700 or PSR-2700 automatically "plays" the recorded performance in precise detail. NOTES • Never use MIDI cables longer than about 15 meters, since cables longer than this can pick up noise which can cause data errors. 73
