Synchronization Using the 
VS-1824 as the Slave
When you want to use the MIDI sequencer as the master to 
control the VS-1824, use the following procedure:
1. Connect the VS-1824 and the MIDI sequencer as shown 
in the following illustration.
fig.08-04
2. Hold [SHIFT] and press [EXT SYNC]. The Sync/Tempo 
screen appears in the display.

3. Use [
], [
], [
], and [
] to move the 
cursor and use the TIME/VALUE dial to change the 
settings.
Sync Error Level
This sets the interval (0-10) for checking MTC reception 
when synchronizing the VS-1824 to MTC transmitted by 
an external MIDI device. When MTC is not sent 
continuously, the VS-1824 checks the MTC and cancels 
synchronization if there is an error. By setting a longer 
interval under such circumstances, synchronization can 
continue, even if there are errors in the source MTC.
Sync MTC Type
This selects the MTC frame rate (30, 29N, 29D, 25,24). 
Select the MTC rate that matches the rate used in your 
MIDI sequencer.
4. Press [PLAY (DISPLAY)] to return to the Playlist display.
5. Set your MIDI sequencer to transmit MTC.
6. Press [EXT SYNC]. The button will begin blinking, 
indicating the VS-1824 is set to synchronize using MTC 
from the external MIDI sequencer.
7. Press [PLAY]. The button blinks green, indicating the VS-
1824 is in MTC receive-standby mode. When the MIDI 
sequencer begins playback and begins transmitting 
MTC, playback will begin on the VS-1824. During 
synchronization, the EXT SYNC indicator and PLAY 
indicator remain lit.

If MIDI Time Code is Unstable
When using MIDI sequencer software for personal 
computers, depending on the hardware specifications 
and the playing conditions, the MTC signal sent to the 
VS-1824 may be unstable. If the synchronization is 
erratic, try using the VS-1824 as the master device, or try 
raising the VS-1824 Sync Error Level as described above.
