Ë A Word About What MIDI Can Do
The letters MIDI stand for Musical Instrument Digital Interface. MIDI is an international standard for allowing
electronic musical instruments equipped with MIDI capability to exchange performance information. For example, a
synthesizer can be used to communicate with a drum machine, an electronic piano can interface with a computer, and
so forth. Additionally, since MIDI is an international standard recognized and implemented by all musical
instrument manufacturers worldwide, instruments made by different manufacturers can communicate with each other
via MIDI.
Ë MIDI Connections
MIDI IN and MIDI OUT
In order to allow communication to take place, all MIDI-equipped instruments have at least two MIDI jacks - MIDI
IN and MIDI OUT. MIDI IN is for receiving MIDI data from another instrument, while MIDI OUT is for sending
MIDI data out to another instrument.
In the example above, the keyboard(s) of the sending or transmitting instrument (MIDI OUT) are being used to
control the sound generators of the receiving instrument (MIDI IN). When a key is played on the sending instrument,
the corresponding note will play on the receiving instrument as though the appropriate key had been pressed on the
receiving instruments's keyboard. When the key is released on the sending instrument, the tone being played by the
receiving instrument will stop. (This is called "Note On / Note Off" data.) The sending instrument is referred to as
the master, while the receiving instrument is called the slave. This is the most basic MIDI hookup.
The above is an example of two-way communication between two MIDI-equipped devices. In this example, the
keyboard(s) of either instrument can be used to control the sound generators of the other.
