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.
