The following MIDI messages are handled 
during synchronization with the DR-670.
● Start
● Timing Clock
● Continue
● Song Select
● Stop
● Song Position Pointer

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.
