Changing The Time Field Display; Synchronizing A Midi Device By Recording Its Tempo Changes On The Br-1200Cd (Sync Track) - Boss BR-1200CD Owner's Manual

Synchronizing external MIDI sequencers and rhythm machines

Changing the TIME field display

Whenever you are transmitting MTC signals from the BR-
1200CD 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 Disp." field and select a time display format
using the TIME/VALUE dial.
Time Disp. (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 "ABSOLUTE," if
necessary, you can set it to "RELATIVE" when you are
transmitting MTC signals from the BR-1200CD 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-1200CD 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-1200CD 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-1200CD's song
time is "01h00m00s00."

song time devices
01h00m00s00 01h30m00s00
01h00m00s00 00h30m00s00
3. Press [EXIT/NO] several times to return to the top
screen.
4. If you wish to store the settings, save the current song
(p. 70).

Synchronizing a MIDI device by recording its
tempo changes on the BR-1200CD (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-1200CD, 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-1200CD while maintaining all of the
originally programmed tempo changes.
