SyncTr:
The Sync Track MIDI Clock is transmitted.
Sync Error Level
This sets the interval (0-10) for checking MTC receiving
status when synchronizing to MTC from an external
MIDI device. If MTC is not being sent continuously, the
VS-1680 checks the MTC and if there is an error,
temporarily cancels synchronization. Selecting a longer
interval under such circumstances will allow
synchronization to continue, even if errors are present.
Normally, this is set to “5.”
Sync MTC Type (MTC Type)
This selects the type of MTC (30, 29N, 29D, 25, or 24). Set
this to conform to the type of MTC on the slave VS-1680.
Syncing Two VS-1680s with
MTC and MMC
The VS-1680 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-1680s using MTC and MMC. One 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. 64)

* In this example, you can use the master’s Stereo In function
for the mix balance between the master and slave VS recorders
(p. 185) First adjust the individual track balances on both
machines. Of course, you can also send the output of both
recorders to an external mixer.
Settings for the Master VS
1.
Hold [SHIFT] and press [F5 (SYSTEM)]. The System
Menu appears in the display.
If the System Menu does not appear, press [F6 (EXIT)].
2.
Press [F4 (MIDI)]. If “MIDI” does not appear above [F4],
press [PAGE] until “MIDI” appears, then press [F4
(MIDI)].
3.
Use [ ], [ ], [ ], and [ ] to move the
cursor and use the TIME/VALUE dial to make settings
for each parameter as described below.
Device ID
This should be set to “17.”
MIDI Thru (MIDI Thru Switch) = OUT
For this application, set this to “OUT.”
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. 25)
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.
Sync Source
For this application, set this to “INT.”
Sync Gen. (Generator)
For this application, set this to “MTC.”
Sync MTC Type (MTC Type)
For this application, set this to “30.”
6.
