MIDI Channels

MIDI allows you to send the data for multiple parts at the same time, with each part

being sent over a separate MIDI channel. There are 16 MIDI channels, numbered 1

through 16, and MIDI channel data is always included whenever you exchange data

(key press etc.)

Both the sending machine and the receiving machine must be set to the same channel

for the receiving unit to correctly receive and play data. If the receiving machine is set

to Channel 2, for example, it receives only MIDI Channel 2 data, and all other

channels are ignored.

With this keyboard, messages received over MIDI Channels 1, 2, 3, 4, and 10 can be

used for multi-timbre play of up to five different instrument parts. The tone and

volume settings for these five channels must be controlled by messages sent from an

external device.

Conversely, keyboard operations are sent to external devices over MIDI Channel 1.

■ General MIDI

General MIDI standardizes MIDI data for all sound source types, regardless of

manufacturer. General MIDI specifies such factors as tone numbering, drum sounds,

and available MIDI channels for all sound sources. This standard makes it possible

for all MIDI equipment to reproduce the same nuances when playing General MIDI

data, regardless of the manufacturer of the sound source.

Though the sound source of this keyboard is not General MIDI compatible, you can

still connect the keyboard to a computer or other MIDI equipment to playback

General MIDI data that is widely available in stores, over computer networks, and

from other sources.

Notes

• General MIDI data made up of a large number of parts may not play correctly on this

keyboard.

• You will have most success playing back General MIDI data that has few parts and is

made up of data on channels 1, 2, 3, 4, and 10.

Messages

There is a wide variety of messages defined under the MIDI standard, and this

section details the particular messages that can be sent and received by this keyboard.
