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-1680.

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-

1680, 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-1680 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-1680,

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.

Creating A Tempo Map

1. Hold [SHIFT] and press [TAP]. The Tempo Map screen

appears in the display. Tempo Map 1 (the starting

tempo) is displayed.

2. Press [ ], [ ], [ ], and [ ] to move the

cursor and use the TIME/VALUE dial to change the

settings as desired.

(Tempo)

Sets the tempo (25.0-250.0) of each tempo map

Meas (Measure)

Selects the measure number of the song (1-999) where

the next tempo map starts.

Beat

This sets the tempo map time signature (1/1 to 8/1, 1/2

to 8/2, 1/4 to 8/4, 1/8 to 8/8). The function buttons

work as shown below.

[F2 (New)]:

Adds a new tempo map to the current ending

location.

[F3 (Ins)]:

Inserts a new tempo map at the current position of the

cursor.

[F4 (Del)]:

Deletes a tempo map at the position of the cursor.

[F6 (EXIT)]:

Exits the Tempo Map screen.

* Tempo Map 1 is the song’s initial tempo. You cannot delete

Tempo Map 1.
