Move the cursor to “Sync Generator” and select “MTC”
using the TIME/VALUE dial.

The BR-1600CD will now be set up to transmit MTC
signals.

Move the cursor to “MTC Type” and select a suitable
MTC type using the TIME/VALUE dial.

You will need to match the BR-1600CD’s MTC type to that
used on the external MIDI sequencer. For more information
regarding setting methods for the MIDI sequencer, refer to
its user’s manual. For more details regarding MTC types,
refer to “About MTC types” below.

Start playback on the BR-1600CD.

As playback starts, the MIDI sequencer will also start to
play in sync.

When the required settings have been made, press
[EXIT/NO] several times to return to the top screen.

When using MTC, settings must be made in order to
synchronize the MIDI sequencer to an external MTC
source; when using the MIDI timing clock, settings must
be made in order to synchronize the MIDI sequencer to
an external MIDI timing clock source.

About MTC types

The following types of MTC can be selected on the BR-
1600CD. After checking your MIDI sequencer’s
specifications, set the BR-1600CD’s MTC type accordingly.

30 frames per second non-drop format. This
format is generally used with audio devices
such as analog tape recorders and with NTSC
black-and-white video devices (as used in Ja-
pan and the US).

29N

29.97 frames per second non-drop format. This for-
mat is generally used with NTSC color video devic-
es (as used in Japan and the US).

29D

29.97 frames per second drop format. This for-
mat is generally used with NTSC-broadcast color
video (as used in Japan and the US).

25 frames per second frame-rate format. This for-
mat is generally used with SECAM and PAL
type video (as used in Europe and elsewhere),
with audio devices, and with movies.

24 frames per second frame-rate format. This for-
mat is generally used with movies in the US.

Drop and non-drop MTC formats

NTSC-type video recorders use two different types
of MTC format - namely, drop and non-drop.
Whereas frames are continuous with the non-drop
format, in order to provide support for NTSC-type
color video, drop format MTC skips two frames
every minute other than the 10th, 20th, 30th, 40th,
and 50th minutes.
Generally speaking, it is easier to work with
continuous frames when creating music or video,
and as a result, non-drop formats are more
commonly used. However, drop-format MTC is
often used in broadcasting facilities where the time
code must be matched to the actual clock time.
