Can Do Using MIDI Control
Can Do Using MIDI Control
MIDI is an acronym for “Musical Instrument Digital
Interface,” and is a standard by which electronic musical
Instruments and computers can exchange musical data. 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.

Moreover, by using an optional AR-3000 to create and edit
phrases, the following is also possible. For detailed

operation.
What is MMC (MIDI Machine Control)?
MMC refers to MIDI messages that were devised in accord
with certain agreements as to how to facilitate the centralized
control of a multiple number of recording devices using one
device. In addition to playback, stopping, and fast
forwarding of songs, you can also select tracks for recording
and carry out other operations merely by operating the one
device which functions as the master. Use of MMC signals
requires that the other devices be capable of remote
operation using MMC signals.

The AR-200 can work as a remote device, starting and
stopping recording and playback of audio phrases when
MMC signals are received.

(operating device = sending side) and slave (receiving side)
and MTC synchronization master and slave.

and MTC synchronization master and slave.
What is MTC (MIDI time code)?
MTC consists of MIDI messages that were devised to allow
MIDI devices to synchronize correctly with professional-use
tape recorders, video equipment, and the like. It differs from
MIDI Clock, displaying the absolute time. The master device
transmits the current absolute time (in hours/minutes/
seconds/frames from the start), and the time of the slave
device is advanced to conform with it. Use of MMC signals
requires that the other device is capable of synchronization
using MTC.
