About MIDI
The D2 records and plays back MIDI musical data, and when
MIDI musical data is received its sound generator will
produce sound.
MIDI (Musical Instrument Digital Interface) is a standard
specification that allows musical data to be exchanged
between electronic musical instruments and computers.
Devices that have a MIDI connector can be connected using a
MIDI cable, allowing them to transmit and receive data.
Today, MIDI is found on virtually all electronic musical
instruments. Without MIDI, it would not be possible to use
an external keyboard to play the D2, or to use the D2 to
record and play back a performance played on an external
keyboard. Although you can use the D2 without knowing
much at all about MIDI, you might also want to take full
advantage of the possibilities offered by electronic musical
instruments. This chapter will provide a simple explanation
of the D2's MIDI-related functionality.
About MIDI connectors
The D2 has two kinds of MIDI connectors.
• MIDI OUT Connectors
These connectors transmit MIDI messages to external
MIDI devices. These can also be used as connectors from
which data received from the MIDI IN connector are
directly transmitted. (Refer to SOFT THRU (p. 77).)
• MIDI IN Connectors
Performance messages from an external MIDI device are
received here. The D2 can receive these messages to play
notes or select sounds, etc.

MIDI Channels
MIDI is able to transmit 16 parts of independent musical data
over a single MIDI cable. This is made possible by the
concept of "MIDI channels." MIDI channels allow messages
intended for a given instrument to be distinguished from
messages intended for another instrument. There are sixteen
MIDI channels (1–16), and normally the transmitting device
must be set to the same MIDI channel as the receiving device
in order for messages to be received.
With the factory settings, the D2's AUTO CHANNEL setting
is ON. (p. 77) In this condition, an external MIDI keyboard
will be able to play the patch of the current part, regardless of
its transmit channel setting.
* The transmit/receive channel settings of each part are as
follows. It is not possible to change the channel settings of each
part.
