MIDI
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 MPS20 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 MPS20 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 MPS20 to the MIDI In of another instrument, you can play
the sounds of both instruments simultaneously from the MPS20 keyboard.
