Unitor Synchronization settings in Logic Pro
Unitor Synchronization settings are only available when Advanced Editing is selected
in Advanced preferences.
You can use these settings to edit the major synchronization parameters for the Unitor8
MIDI interface.
SMPTE Mode buttons: You can instruct the Unitor8 to read or write SMPTE data.
Read: Select to read SMPTE data.
Generate: Select to write SMPTE data.
SMPTE Mode Refresh checkbox: Activates Refresh mode, where fresh timecode is
generated, in sync with received timecode. Refresh mode works with both VITC and LTC
(see below). You should always use Refresh mode whenever you need to copy an LTC
track, because you can’t directly copy LTC without a considerable loss of quality. When
copying entire multitrack tapes, you should patch all tracks directly, but refresh the
timecode track via the Unitor8.
Note: You should only use Refresh mode if you are copying timecode.
SMPTE Type buttons: Define the SMPTE format that you want to use.
LTC: Longitudinal (also called Linear) Time Code is written to a tape track.
VITC: Vertical Interval (or Vertically Integrated) Time Code is written invisibly to a
videotape.
Off: No timecode is written.
Freewheel slider: Specifies how long the synchronizer continues transferring MTC to
the sequencer, after timecode ceases to be read. The freewheel parameter affects the
SMPTE reader. You can set the freewheel time (in frames) for LTC and VITC.
Long freewheel times can maintain synchronization, even if there are dropouts in the
timecode, but they also increase the reaction time of Logic Pro after the timecode
transmitter stops. In practice, you should set a value that’s as large as necessary (for
sustained operation), and as small as possible (to reduce waiting times).
