Controlling the AR-200 with MIDI
Signals (MIDI control)
What is MIDI Control?/What You
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.
• You can record and play back MIDI signals from an
external MIDI device in the same manner as with audio
phrases.
• You can use MIDI signals from an external MIDI device
as control signals for controlling playback of audio and
MIDI phrases.
• You can use received MMC signals to start and stop
recording and playback of audio phrases.
Moreover, by using an optional AR-3000 to create and edit
phrases, the following is also possible. For detailed
information, please refer to the AR-3000 user’s manual.
• You can use MMC and MTC signals from an external
MIDI device for remote control and synchronized
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.
However, there is no connection between MMC master
(operating device = sending side) and slave (receiving side)
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.
Refer to the "MIDI Implementation" (p. 64) for easy
confirmation of the MIDI messages that can be sent and
received by the AR-200 along with the more detailed MIDI
specifications in
"MIDI Implementation" (p. 58).
Playback of Phrases Using
MIDI Signals
MIDI signals from an external MIDI device can be used as
control signals in order to play back audio and MIDI phrases.
Phrase playback can be controlled by the different types of
MIDI messages, including Note On/Off, Note On Velocity,
Panpot, and Expression.
* MIDI phrases cannot be played back simultaneously with
audio phrases or other MIDI phrases.
