Chapter 8 Use with MIDI Devices

Using the Tempo Map (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.
This section gives an explanation of how to control the
MIDI sequencer from the VS-1680 using the tempo
map.
What is a Tempo Map?
A tempo map is a song's measure, beat, and tempo
information. Transmitting this information to MIDI
sequencers and other devices, it can be used in syn-
chronizing operations with external MIDI devices. The
tempo map sets tempo changes for each measure, so
you can record information specifying changes in
rhythm and tempo to be played from any designated
measure. With the VS-1680, tempo maps are num-
bered 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. Up to
50 tempo maps can be created.
