Synchronizing with MIDI Devices

Section 6

25: 25 frame per second frame rate. This is used

for SECAM or PAL format video, audio

equipment, and film (used in Europe and

elsewhere).

24: 24 frame per second frame rate. This is used

for video, audio devices, and film in the US.

6. Press [UTILITY] (or press [EXIT] repeatedly) to return

to the Play screen.

* During updating, “Keep power on!” appears in the upper line

of the display, while the lower line shows what is being

processed.

7. Just as when you synchronize a MIDI sequencer using

external MTC, when you use the MCK, you can

synchronize the MIDI sequencer using the external

MIDI clock.

8. Get the MIDI song data ready for playback.

When the BR-900CD begins playing, the MIDI sequencer

will also begin playing in sync with it.

Setting the MTC offset

The offset sets the time required to align the song playback

and MTC timing when synchronizing an external device

using MTC from the BR-900CD.

1. Press [UTILITY].

2. Press CURSOR [ ] [ ] to move the cursor to

“SYNC,” and press [ENTER].

3. Press CURSOR [ ] [ ] to select “Offset,” and turn

the TIME/VALUE dial to set the time offset.

fig.05-408d

The offset is set as the difference between the “time to

which to align the MTC timing” and the “time to which

to align the song timing.” For example, you want to have

the external device play back with the MTC timing

shown below when the song timing reaches

“01h00m00s00,” then set the offset as follows.

4. Press [UTILITY] (or press [EXIT] repeatedly) to return

to the Play screen.

* During updating, “Keep power on!” appears in the upper line

of the display, while the lower line shows what is being

processed.

What are drop and non-drop formats?

There are two types of format used by NTSC video

cassette recorders, non-drop and drop. With the non-

drop format, the frames are continuous. On the other

hand, in order to support NTSC color video, the drop

format drops the first two frames of every minute

excluding minutes 10, 20, 30, 40, and 50.

In most video and audio production, since formats with

continuous frames are easier to deal with, non-drop is

generally used. In contrast, in situations such as in

broadcast, where the time code must match actual clock

time, drop is used.
