SY-200: Can the SY-200 transmit or recognize MIDI clock?

Yes. The SY-200 can transmit and recognize MIDI Clock.

Use a TRS MIDI cable to connect from the MIDI jacks (IN/OUT) of the SY-200, to an external MIDI device that transmits, or receives MIDI clock.
For details about compatible TRS MIDI cables, see "SY-200: What kind of MIDI cable can I use?". 

Set the MIDI parameters as needed for MIDI Time Sync or MIDI TX/RX Transmit/Receive.

For MIDI TIME SYNC parameter settings:

1. Press the [MENU] button.
   The unit enters MENU mode.

5. Press the [3] knob to select SYNC.
6. Turn the [MEMORY] knob to specify the tempo clock to which the SY-200 synchronizes.
   INTERNAL (default): Synchronizes to the internal SY-200 tempo.

   If you're using the SY-200 as a Master, choose INTERNAL.
   If you’re using the SY-200 as a remote/replicant MIDI slave device, choose “AUTO.”

   The unit exits MENU mode.
