Synchronizing Operation to

What Is MTC?/Synchronized
Playback with Video Equipment
and Other Devices
What Is MTC (MIDI Time Code)?
This comprises MIDI messages developed to allow MIDI
devices to be synchronized with precision. It differs from
MIDI Clock in that it displays 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.
With the AR-3000R, you can combine MMC and MTC signals
to synchronize playback of audio phrases with a digital
mixer, video equipment, or other devices.
Types of MTC (Frame Rate)
The MTC types (frame rates) you can select with the AR-
3000R are shown below. When you are synchronizing
operation using MTC, you need to set both devices to
matching frame rates. Check the specifications of the
connected external MIDI instrument, then make the settings.
