Synchronizing external MIDI sequencers and rhythm machines
Changing the TIME field display
Whenever you are transmitting MTC signals from the BR-
1600CD in order to synchronize an external MIDI device, you
will be able to change the way in which time is displayed in
the TIME field.
1. On the Sync Parameter screen, move the cursor to the
“Time Display Format” field and select a time display
format using the TIME/VALUE dial.
Time Display Format
This parameter is used to make settings for the standard
time indicated in the display’s TIME field. Although the
display format is normally set to “ABS,” if necessary,
you can set it to “REL” when you are transmitting MTC
signals from the BR-1600CD in order to synchronize an
external MIDI device.
ABSOLUTE TIME
A specified offset time will be added to the display time.
RELATIVE TIME
The song’s start time is displayed as “00:00:00-00.00.”
2. Move the cursor to “Time Offset” and select a suitable
offset time using the TIME/VALUE dial.
An offset time is used whenever synchronizing external
MIDI devices to the BR-1600CD using MTC in order to
align the MTC time with respect to the song time.
In specific terms, the offset is determined by subtracting
the desired playback time on the BR-1600CD from the
desired playback time on the MTC-synchronized
external MIDI devices.
For example, the following offset times can be set in
order to have external MIDI devices play back at the
MTC times shown below when the BR-1600CD’s song
time is “01h00m00s00.”
3. Press [EXIT/NO] several times to return to the top
screen.
Synchronizing a MIDI device by recording its
tempo changes on the BR-1600CD (Sync Track)
You can use the procedure described below to receive MIDI
timing clock signals from an external MIDI sequencer or
rhythm machine on the BR-1600CD, to detect the tempos of
the MIDI device’s playback, and to automatically create
rhythm tempos based on these.
A tempo recording created in this way is known as a Sync
Track, and when used together with MIDI timing clock
signals, you will be able to synchronize the external MIDI
device to the BR-1600CD while maintaining all of the
originally programmed tempo changes.
● A sync track must be created before
synchronization is possible.
1. Set up the MIDI sequencer or rhythm machine as the
synchronization master and enable the transmission of
MIDI timing clock signals.
For more information regarding setting methods for the
MIDI sequencer or rhythm machine, refer to its user’s
manual.
2. Using a MIDI cable, connect the BR-1600CD to the
MIDI sequencer as shown in the following diagram.
fig.50-10
3. Press [UTILITY].
The Utility Menu screen will appear.
