Can Do with MIDI Control
MIDI stands for “Musical Instrument Digital Interface,” and
is a unified worldwide standard allowing the exchange of
performance information and the like between electronic
instruments and computers. You can connect any device
conforming to the MIDI standard with a MIDI cable, and
then transmit performance data and control the device’s
operation and settings.

Glossary of Selected MIDI Terms
MIDI messages:
These are messages conveyed by MIDI
signals. These messages are necessary for playing
performances on an external MIDI sound generating device.
They include note messages for playing and stopping notes,
as well as Control Change and System Exclusive (SysEx)
messages, which can modify and enhance the expressive
capabilities of performances.

Note number:
This is a number assigned to each key (note)
on the keyboard of an electronic musical instrument.
Numbers are assigned in semitone steps, with middle C (C4)
set at 60 and the numbers from 0 to 127 indicating the

sets in groups of 100.
Control Change:
MIDI instrument performances use a
variety of controllers, not just for the keyboard. The MIDI
message that conveys such controller action is the Control
Change. The AR-3000R receives and acts upon Panpot and
Expression messages.
