Simultaneously press the [DEMO] and [START/STOP] button to enter the MIDI/Utility mode. An
“mm” appears in the display indicating the MIDI/Utility mode.
When the DD-55 is connected via MIDI to another MIDI device — such as a sequencer or rhythm
machine — you can have the two devices play back in perfect synchronization. To do this properly,
you have to make sure that the time based functions (song playback, etc.) on each device are properly
set, as to whether they are controlled by internal clock or external clock. When the internal clock (I)
is enabled on the DD-55, timing will be controlled by the DD-55’s internal clock. When external
clock (E) selected, the DD-55 will synchronize to the external sequencer’s or computer’s clock.
I (Internal) ...............The DD-55’s clock is used as the timing clock.
E (External)...............The external clock is used as the timing clock (If the clock is set to
external without being connected to another MIDI device, the DD-55’s
Song Play or Demo functions will not operate.)
1 Display the clock setting.
2 Set the Clock to External/Internal.

Enter/Exit the MIDI/Utility Mode
• Pads and pedals do not sound while in the MIDI/Utility mode.
To exit the MIDI mode, once again simultaneously press the [DEMO]
and [START/STOP] buttons. The DD-55 exits from the MIDI mode
and returns to the normal play mode.
Setting the Clock
After entering the MIDI/Utility mode, press the [DRUM 1] button to
see the current setting for the MIDI clock.
To set the clock to “I” (external), turn the DIAL to the right (clock-
wise). To set the clock to “E” (internal), turn the DIAL to the left
(counter-clockwise).
After the clock is set, exit the MIDI/Utility mode.
• The default MIDI clock setting is “I” (internal).
