MIDI

MIDI stands for Musical Instrument Digital Interface. This is a world-wide standard communication interface

that enables electronic musical instruments and computers (of all brands) to communicate with each other so

that instructions and other data can pass between them. This exchange of information makes it possible to

create a system of MIDI instruments and devices that offer far greater versatility and control than is available

with isolated instruments. Whether you interface with computers, sequencers, expanders or other keyboards

your musical horizons will be greatly enhanced.

MIDI CONNECTION

The MIDI terminals are located on the left side panel of the piano.

1. MIDI IN: This terminal receives MIDI data from an external MIDI device.

2. MIDI OUT: This terminal transmits data from this instrument to other

MIDI devices. The transmitted data includes the note and touch velocity

produced while playing on the keyboard as well as voice changes, wheel

operation, and recorded playback for the melody tracks. Demo songs

are not transmitted.

NOTE: For more information regarding transmitted MIDI data, please see

the next page and/or the MIDI implementation chart.

MIDI CHANNEL: The MIDI system in this unit has 16 channels numbered from 1-16. Each of the channels

is responsible for a voice. When the instrument receives MIDI information from an external device, the active

channel is determined by the control message. The transmission channels on this keyboard are ﬁxed as follows:

Channel 1: Master voice (keyboard)

Channel 2: Layer voice (keyboard)

Channel 3: Split voice (keyboard)

Channel 4: Track 1, playback, Master Voice

Channel 5: Track 1, playback, Layer Voice

Channel 6: Track 2, playback, Master Voice

Channel 7: Track 2, playback, Layer Voice

Channel 8: Track 3, playback, Master Voice

Channel 9: Track 3, playback, Layer Voice

Please see the MIDI Implementation Chart for more detail.
