Midi Synchronization Using The Midi Clock - Sony MDM-X4 Operating Instructions Manual

MIDI Synchronization Using the
MIDI Clock
You can use the MIDI clock to synchronize this unit
with sequencers (etc.) that are not MTC (MIDI Time
Code) compatible. A tempo map must be created in
order to use the MIDI clock.
Notes
• When using the MIDI clock for synchronization, be sure to
create the tempo map before you start recording (see
"Creating a tempo map" to the right for details). Also, be
sure to listen to the MIDI sound source coming from the
sequencer before you start recording.
It is extremely difficult to create a perfect match between a
recorded song and the timing of the tempo map.
Therefore, if you create a tempo map after recording, the
synchronization will be incorrect.
Tempo information will not be stored on the disc if you
create a tempo map but do not make an actual recording.
• When using a sequencer that supports MIDI clock and
MIDI song position, you can start playback from an
arbitrary position in the song. At this time, the sequencer
locates the current song position and starts running in
sync. Some sequencers, however, may not be able to
follow this unit when you use this unit's locate function.
Be sure to check the sequencer's search before sychronized
operation.

Setup
1
Set this unit's "SYNC" system setting to MCLK.
See "Changing a Setting" (page 18) for details.
2
Set the sequencer to accept external MIDI clock
synchronization.
This enables playback of MIDI song data.
Refer to the operating instructions supplied with
your sequencer as well.
3
Start playback from this unit.
The sequencer starts playing in sync with this
unit.

Creating a tempo map
Setting up tempo information creates the standard
signal for synchronization and allows you to use the
MIDI clock for synchronization with an external
sequencers (etc.).
You can assign up to 50 tempo maps to each song.
EXAMPLE: Suppose we create the following tempo
maps.
Bar 1 Bar 9
4 / 4 /
4 4
=120
In this case, the tempo will change as shown below
Bar 1~8 4 / time
4
Bar 9~16 4 / time
4
16
Bar 17~ / time
16

The following step show you how to make the tempo
map shown in the previous example.
1
Press EDIT.
[EDIT] appears in the display.
2
Turn the jog dial so that "Song Tempo" appears in
the display.
The name of the edit function starts blinking in
the display.
