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
sequencer), and computers. MIDI enables MIDI equipped devices designed by different manufacturers
the ability 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 MP20 is equipped with conventional MIDI In and Out ports and a USB port.
MIDI Channels
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 33 for the details.
MIDI In and Out Ports
The MP20 is equipped with the 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 MP20 to the MIDI In of another instrument, you can play the sounds
of both instruments simultaneously from the MP20 piano.
When you connect the MIDI In of the MP20 to the MIDI Out of another controller, you can control the MP20
using the other controller.
