Using The Sync Track (Master) - Roland VS-1680 Owner's Manual

4. Press [PLAY (DISPLAY)].
Return to Play condition.
5. Set your MIDI sequencer to send MTC.
6. Press [EXT SYNC].
The button indicator blinks, indicating that the VS-
1680 is synchronized using the MTC from the MIDI
sequencer.
7. Press [PLAY].
The button indicator blinks green, indicating that the
VS-1680 is in MTC receive standby mode. When the
MIDI sequencer begins playback, then playback also
begins on the VS-1680. During synchronization, the
EXT SYNC indicator and PLAY indicator are lit.
Synchronizing with an External MIDI
Device
When the VS-1680 is running under the control of the
MTC from an external MIDI device, you can synchro-
nize the song's playback time and the MTC time. This
time is called the offset. For example, if the MTC time
is "01h00m00s00f00," and the song's time is
"00h10m00s00f00," the "offset" is as follows.
(Offset)
= (MTC time) - (destined time of the song)
= (01h00m00s00f00) - (00h10m00s00f00)
= (00h50m00s00f00)
If the offset value turns out to be negative, add
"24h00m00s00f00" to the MTC time before subtracting
the destined time of the song. For example, if the MTC
time transmitted is 00h00m50s00f00," and you want
the song to play back at "00h01m00s00f00," then the
offset works out as shown below.
(Offset)
= (MTC time) - (destined time of the song)
= (00h00m50s00f00) - (00h01m00s00f00)
= (24h00m00s00f00) + (00h00m50s00f00) -
(00h01m00s00f00)
= (23h59m50s00f00)
* With the VS-1680, continuous playback from
"23h59m59s29f99" to "00h00m00s00f00" does not corre-
spond to (overnight mode). The song that crosses over
"00h00m00s00f00" momentarily stops at
"23h59m59s29f99" then resumes playback.

Offset
When the VS-1680 is running under the control of the
MTC from an external MIDI device, you can synchro-
nize the song's playback time and the MTC time. The
offset settings range varies depending on the MTC
type selected for the current song.
Time Display Format
Select one of the reference times (REL, ABS) that
appear in the display. For now, choose "ABS."
REL: The starting time of the song is displayed as
"00h00m00s00f00."
ABS: The time displayed includes the addition of the
offset time.
5. Press [PLAY (DISPLAY)].
Return to Play condition.

Using the Sync Track (Master)

If your MIDI sequencer supports Song Position
Pointer messages, you can use the MIDI Clock to syn-
chronize operations. There are two methods of syn-
chronization using the MIDI Clock: one is using the
sync track, and the other one is using the tempo map.
Here is an explanation of how to control the MIDI
sequencer from the VS-1680 using the sync track.
