● Start
● Timing Clock

● Song Select

■ Setting Sync Mode
Select whether the DR-670 is to be the master or
slave in Sync mode.
fig.09-06
AUTO:
Master and slave are switched
automatically.
While the DR-670 normally functions as the
master, when the performance is stopped
and a Start message is input from an
external MIDI device, the DR-670
automatically switches to slave.
INT:
The DR-670 functions as the master.
Operating the DR-670 starts and stops
performances, and performances play at the
tempo set in the DR-670.
MIDI:
The DR-670 functions as a slave device.
The DR-670 starts and stops according to the
messages input from an external MIDI
device, and performances are synchronized
to the timing clock transmitted by the
external MIDI device.
* Sync mode settings are not saved. The function is
always set to “AUTO” when the DR-670’s
power is turned off.
Tempo Display with the DR-670 as Slave
When the DR-670 is functioning as a slave
device, the tempo appears in the display as
shown below, and the tempo cannot be
controlled from the DR-670.
fig.09-07
If no timing clock is being transmitted by the
external source when [START] is pressed, then
the tempo indicator lights and remains lit, and
the start of the performance is put on hold until
the timing clock arrives.
* You cannot switch modes while the DR-670 is in
this state. To switch modes, press [STOP/
CONT], then proceed to switch the mode after
the tempo indicator has gone out.
