●MIDI Time Code Quarter Frame Messages
MIDI Time Code Quarter Frame Messages can be transmitted while the sequencer is
running (Playing or Recording) if the Sync Mode parameter (SYSTEM/TEMPO/SYNC) is
MASTER and MTC Sync Output parameter (SYSTEM/MIDI/MMC MTC) is ON. The
transmitted time counts are summed to MTC Offset Time parameter (SYSTEM/MIDI/
MMC MTC) as the song top is "00:00:00:00."
The sequencer synchronizes with the time counts which are summed to MTC Offset Time
parameter (SYSTEM/MIDI/MMC MTC) as the song top is "00:00:00:00" if the Sync Mode
parameter (SYSTEM/TEMPO/SYNC) is SLAVE(MTC).
