MIDI
What is MIDI?
The letters MIDI stand for Musical Instrument Digital
Interface, which is the name of a worldwide standard for
digital signals and connectors that makes it possible to
exchange musical data between musical instruments and
computers (machines) produced by different manufacturers.
MIDI compatible equipment can exchange keyboard key
press, key release, tone change, and other data as messages.
Though you do not need any special knowledge about MIDI
to use this keyboard as a stand-alone unit, MIDI operations
require a bit of specialized knowledge. This section provides
you with an overview of MIDI that will help to get you going.
MIDI Connections
MIDI messages are send out through the MIDI OUT terminal
of one machine to the MIDI IN terminal of another machine
over a MIDI cable. To send a message from this keyboard to
another machine, for example, you must use a MIDI cable to
connect the MIDI OUT terminal of this keyboard to the MIDI
IN terminal of the other machine. To send MIDI messages
back to this keyboard, you need to use a MIDI cable to connect
the other machines MIDI OUT terminal to the MIDI IN
terminal of this keyboard.
To use a computer or other MIDI device to record and
playback the MIDI data produced by this keyboard, you must
connect the MIDI IN and MIDI OUT terminals of both
machines in order send and receive data.
To use the MIDI THRU function of a connected computer,
sequencer, or other MIDI device, be sure to turn this

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, pedal operation, 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.
This keyboard is equipped with multi-timbre capabilities,
which means it can receive messages over all 16 MIDI
channels and play up to 16 parts at the same time.
Keyboard and pedal operations performed on this keyboard
are sent out by selecting a MIDI channel (1 to 16) and then
sending the appropriate message.
