MIDI OVERVIEW
The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for
connecting synthesizers, sequencers (MIDI recorders) and other electronic instruments so that they can
exchange performance data.
The CN31 is equipped with two MIDI jacks for exchanging data: MIDI IN and MIDI OUT. Each uses a
special cable with a DIN connector.
MIDI IN : For receiving note, program change and other data.
MIDI OUT : For sending note, program change and other data.
MIDI uses channels to exchange data back and forth between MIDI devices. There are receive (MIDI IN)
and transmit (MIDI OUT) channels. Most musical instruments or devices with MIDI functions are equipped
with both MIDI IN and OUT jacks and are capable of transmitting and receiving data via MIDI.
The receive channels are used to receive data from another MIDI device and the transmit channels are
used to transmit data to another MIDI device.
Connection to an external sequencer
When connected as shown in the illustration below, songs played on the CN31 can be recorded using
a MIDI recorder, with preset sounds (such as piano, harpsichord and vibraphone, etc.) controlled by the
CN31’s MULTITIMBRAL MODE function to create a multi-layer MIDI recording.
