MIDI Overview
The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for connecting
musical instruments, computers, and other devices to allow the exchange of performance data.
MIDI Terminals

MIDI IN
Receiving note, program change, and other data.
MIDI OUT
Sending note, program change, and other data.
MIDI channels
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.
The illustration below shows three musical instruments, connected together using MIDI.

For both receiving and transmitting, channels 1-16 can be used.
Recording/playing with a sequencer
When connected to a sequencer (or a computer running MIDI
sequencing software), the CN39 digital piano can be used to
record and playback multi-track songs, with separate sounds
playing simultaneously on each channel.
