The sequencer is set up to transmit MMC com- mands, and is set so that it synchronizes to SMPTE/MTC.

When a “transport” command is given from the sequencer, the appropriate MMC command is transmitted to the DA-98. When the DA-98 has located and starts playback (or recording), the MTC is transmitted back to the sequencer, which locks in and starts at the correct point.

In this way, though the DA-98 is the timecode master, the sequencer is the transport master.

The arrangement shown here uses 2 inputs to the sequencer. The same effect could be achieved with the intelligent use of filtering mechanisms.
