          ensure that you have defined at least one MIDI port in your
          ardour.rc file. The default configuration includes a single port
          that is part of the ALSA MIDI router/sequencer system.

          if you have more than one MIDI port, click on the button in the
          <guilabel>MTC</guilabel> column for the port you plan where MTC
          will be received.

          if you have more than one MIDI port, then you should probably
          click on the button in the <guilabel>MMC</guilabel> column for the
          port you plan where MMC will be received. This is not required,
          but many devices that send MTC also send MIDI Machine Control
          commands and may not be able to control Ardour correctly unless
          Ardour is also responding to MMC.

      To test that Ardour is now slaved, press the
      <guibutton>Play</guibutton> button on the MTC master, or some other
      action that will cause it to start transmitting MTC. Ardour should
      jump to the position indicated by incoming MTC, and start playing.
      Press <guibutton>Stop</guibutton> on the master (or do some other
      action that will cause the master to stop sending MTC) and Ardour
      should stop at the precise time indicated by the master.
