Chapter 22 Specific Applications

Syncing Two VS-1824s or a VS-1824 and a VS-1680 with MTC and MMC

The VS-1824 has the ability to generate and slave to MIDI Time Code (MTC). It also has the ability to varispeed its sample rate to account for fluctuations in the source clock signal. This provides a sync that is frame-accurate and allows you to do things such as lock to video and locate on the fly. The following example explains how to synchronize two VS-1824s using MTC and MMC. One VS-1824 or VS-1680 acts as the MMC/MTC master, and the other acts as the MMC/ MTC slave. Make connections as described below:

MMC (See Appendices p. 12)

SysEx.Tx (System Exclusive Transmit Switch)

For this application, set this to “On.”

MMC (Midi Machine Control Mode)

For this application, set this to “MASTER.”

Control Type (Mixer Control Types)

For this application, set this to “Off.”

*When “C.C.” or “Excl” is selected, mixer adjustments made on the master VS will result in the same mixer settings occurring on the slave VS. For more detailed information about System Exclusive messages, refer to “MIDI Implementation” (Appendices p. 82)

4.	Hold [SHIFT] and press [EXT SYNC].
5.	Use [	], [	], [	], and [	] to move the
	cursor and use the TIME/VALUE dial to make the
	settings as described below.

	For this application, set this to “INT.”

INPUT 7, 8

MIDI OUT

MASTER

MASTER L, R MIDI IN

SLAVE

Sync Gen. (Generator)

For this application, set this to “MTC.”

Sync MTC Type (MTC Type)

For this application, set this to “30.”

6. Press [PLAY (DISPLAY)] to return to the Playlist display.

*In this example, you can use the master’s Stereo In function for the mix balance between the master and slave VS recorders (p. 196) First adjust the individual track balances on both machines. Of course, you can also send the output of both recorders to an external mixer.
