USB MIDI Connection
Similar to television channels, MIDI protocol transmits multiple channels of MIDI performance data. Typical
MIDI instruments can play up to 16 channels at the same time. Each channel can be assigned its own voice.
To change and/or assign MIDI channels, enter Function Mode and select the MIDI Channel parameter. See page 19 for the
details.
The M3 digital piano is equipped with conventional MIDI In and MIDI Out ports. If you are new to MIDI, the MIDI In port is used
to receive MIDI data from another MIDI device; and the MIDI Out port is used to transmit MIDI data to another MIDI device.
When you connect the MIDI Out of the M3 digital piano to the MIDI In of another instrument, you can play the sounds of both
instruments simultaneously from the M3 digital piano piano.
In addition to the conventional MIDI In and MIDI Out ports, the M3
digital piano also has a USB (Universal Serial Bus) port on the rear
panel. You can connect the M3 digital piano directly to a computer
with a USB cable. This connection transmits and receives MIDI data
between the M3 digital piano and the computer.
The M3 digital piano supports the “Plug and Play” feature used in
the Windows XP or higher and Macintosh operating systems. No
drivers are required to use this connection; but you may need to
enable MIDI on your computer’s sound and audio control panel.
To use the M3 digital piano as a MIDI controller with a computer,
use any Type-A to Type-B USB cable. By default, the M3 digital
piano acts as a MIDI controller (not a hard drive) when connected
to a computer.
If you have a sequencer program installed on your computer,
you can use this USB connection to record and play your music.
The M3 digital piano‘s recorder is actually a sequencer and the
performance you record into the M3 digital piano’s memory is MIDI
performance data. Using a computer based sequencer program
provides unlimited memory, editing, and posting on the Internet.

MIDI is the acronym for Musical Instrument Digital Interface. It is the industry standard protocol that allows the exchange of musical data between electronic
musical instruments, devices (such as a sequencer), and computers. MIDI enables MIDI equipped devices designed by different manufacturers to communicate
MIDI data to each other.
MIDI data is sent or received using standard MIDI cables to connect to other MIDI devices or a USB cable to connect to a computer.
The M3 digital piano is equipped with conventional MIDI In and Out ports and a USB port.
