5. About MIDI
What is MIDI?
MIDI is an acronym for Musical Instrument Digital Interface, a world-wide standard that allows
you to transfer performance information between electronic musical instruments and computers.
The X5DR is a MIDI tone generator that does not have a keyboard. It receives MIDI data from a
MIDI keyboard, computer, or sequencer to play music.
MIDI connectors receive and transmit MIDI performance data. There are three types of MIDI
connectors: MIDI IN, MIDI OUT, and MIDI THRU. You need to use MIDI cables to connect these
The MIDI IN connector receives data from an external MIDI device, and the MIDI OUT transmits
data to an external MIDI device. The MIDI THRU connector transfers data received at the MIDI
IN connector to the external MIDI device without alteration.
MIDI THRU: Outputs data received at
MIDI IN without alteration.
Connect a MIDI cable to this
connector when you wish to connect
multiple MIDI devices.
• You can connect as many MIDI devices as you want using the MIDI THRU connectors.
However, to avoid a malfunction it is best to connect only up to two or three devices. If you
wish to connect more devices, use a MIDI Patch Bay.
MIDI Channels are used to transfer the data of different instrumental parts (such as drums, bass,
piano, etc.) through a single MIDI cable. There are 16 MIDI channels, and each channel transmits
individual performance data. To playback data via MIDI, it is necessary that the receive channel
and the transmit channel match, like a TV.
For example, the X5DR produces sound by receiving MIDI channel performance data set by the
Global MIDI Channel in Program Play mode. The X5DR receives MIDI channel performance
data set for each Timbre or Track in Combination Play mode or in Multi mode, respectively, to
produce different sounds simultaneously.
MIDI OUT: Transmits the MIDI signal.
This is used to transmit sound data on
MIDI IN: Receives the MIDI signal.
If you wish to play the X5DR from a
MIDI keyboard or computer, connect a
MIDI cable to this connector.
