A master or slave synchronization mode that specifies the
use of MIDI Time Code.
If this mode is used as the master sync mode,
the sequencer gets its timing information from MIDI Time Code
messages. This mode only applies as the master sync
mode to sequencers that are also MIDI receivers. If this
mode is used as the
slave sync mode, the sequencer sends MIDI Time Code
messages to its receiver. (See the MIDI 1.0 Detailed
Specification for a description of MIDI Time Code.)
