Chapter 15 Using External MIDI Devices
7. Use [

], [
], and [
] to move the 
cursor to “Sync Gen.,” and use the TIME/VALUE dial to 
change the setting.
Sync Gen. (Sync Generator)
This setting determines what type of MIDI signal is 
generated at the MIDI OUT connector on the VS-1824. 
For this application, choose “SyncTr.”
Off:
No MIDI signals are transmitted.
MTC:
MIDI Time Code is transmitted.
MIDIclk:
The tempo map MIDI Clock is transmitted.
SyncTr:
The sync track MIDI Clock is transmitted.
8. Press [PLAY (DISPLAY)] to return to the Playlist display.
9. Set your MIDI sequencer to follow the MIDI Clock 
messages received from external devices, and to play 
back MIDI song data. When playback begins on the VS-
1824, the MIDI sequencer will begin playback as well.
Using the Tempo Map
If your MIDI sequencer supports Song Position Pointer 
messages, you can use the MIDI Clock to synchronize 
operations. There are two methods of synchronization using 
the MIDI Clock: one is to use the sync track, and the other is 
to use the tempo map. This section provides an explanation 
of how to control the MIDI sequencer from the VS-1824 using 
a tempo map.
What is a Tempo Map?
A tempo map is a song’s measure, beat, and tempo 
information. By transmitting this information to MIDI 
sequencers and other devices, it can be used to synchronize 
operation with external MIDI devices. The tempo map sets 
tempo changes for each measure, so you can record 
information that specifies changes in rhythm and tempo to 
be played from any designated measure. With the VS-1824, 
tempo map s are numbered sequentially from the beginning 
of the song, with Tempo Map 1 first, followed by Tempo 
Map 2, Tempo Map 3, and so on. Tempo Map 1 is already 
specified at the beginning of the song, and determines the 
initial tempo of the song. To change the tempo at a 
subsequent measure, create a new tempo map at each 
location where you want the tempo to change. You can create 
up to 50 tempo maps per song.
