Chapter 12: MIDI applications

5. Move the cursor to the field, and turn the [JOG] dial to select .

MTC is selected as a sync signal that the DPS12 transmits.

6. Press the [F6] key to set the field to .

7. To change the frame rate of the MTC (default = 30, non-drop), move the cursor to the field,

and turn the [JOG] dial to recall the TIME DISPLAY Control Panel.

8. Move the cursor to the field, and select a frame rate of the MTC from , , (30,

non-drop), , (30 drop).

The field enables you to select a frame rate usually used for the time counter and the time

fields. This setting is also reflected in the rate of the MTC that the DPS12 transmits and receives.

9. Set up the MIDI sequencer so that it will synchronize to an external MTC.

10. Start recording or play back the DPS12.

While the DPS12 is recording or playing, the MTC appropriate for the time value of the DPS12 is transmitted

via the MIDI OUT/THRU jack to the MIDI sequencer, and the MIDI sequencer synchronizes the MTC.

Synchronizing an external device to the DPS12 (MIDI Clock)

This example also uses the DPS12 as a sync master. However, sync signals supplied to an external device do not

constitute MTC, but MIDI Clock plus Song Position Pointer information. MIDI Clock is timing information in

which one beat consists of 24 clocks. Song Position Pointer is position information expressed as bar/beat/clock

values. The merits of MIDI Clock synchronization include the fact that combining MTC and other MIDI messages

does not affect the system, and that you can specify the locate position and edit region using bar/beat/clock values.

This method is suitable for the following applications:

• Using a MIDI sequencer or a workstation-type synthesizer that receives only MIDI Clock as a sync signal

• Recording or playing the DPS12’s mix parameters on a MIDI sequencer in real-time. (See page 116.)

➸

NOTES :

• If you use MIDI Clock as a sync signal, the tempo setting specified on the MIDI sequencer will be

ignored.

• Tempo changes should be executed on the DPS12. (TEMPO MAP)

• Entering the time signature information of the song to which to sync will match the locate position and

edit range to those of the MIDI sequencer.
