The sequencer in the TD-8 can be synchronized to an external device that transmits MIDI clock - i.e. a Sequencer or Recorder. Use the following steps to set the TD-8 to external sync:
1. With a MIDI cable, connect the MIDI OUT of the external MIDI device to the MIDI IN of the TD-8.
2. Press SETUP.
3. Press F2 (MIDI).
4. Press F1 (GLOBAL).
5. Press the DOWN CURSOR button to select "SYNC MODE."
6. Turn the VALUE dial to select "EXT."
Note: When set to "EXT," the TD-8 functions as a slave device and the song selected will play only when receiving a "MIDI Clock" message. The external MIDI device determines the tempo and the TD-8 will follow in "sync" when you start or stop the external unit.
7. Press PATTERN or SONG to return to Pattern Play or Song Play Mode.
