TR-8S, TR-6S: Can I make it synchronize with DAW software or an external MIDI device?

Yes.
The TR-8S and TR-6S support tempo synchronization using MIDI clock.
Perform the following procedure.

1. Press the [UTILITY] button.
   
   - The setting screen appears.
2. Use the [VALUE] knob to select “SYNC/TEMPO: TempoSync”, and press the [ENTER] button (TR-6S: [VALUE] knob).
3. Use the [VALUE] knob to change the value.
   　AUTO: If MIDI clock is input from the MIDI IN connector or the USB port, the tempo automatically synchronizes to MIDI clock. If MIDI clock is input simultaneously from the MIDI IN connector and the USB port, the USB port takes priority.
   　MIDI: The tempo synchronizes to MIDI clock being input from the MIDI IN connector.
   　USB: The tempo synchronizes to MIDI clock being input from the USB port.
   　INT: The tempo operates according to the TR-8S/6S’s own setting. Use this setting if you don’t want to synchronize with an external device.
4. Press the [UTILITY] button to return to the previous screen.
