Chapter 35 Synchronizing Logic Express 857
Some synchronizers send Full Frame Messages (instead of MTC) to locate the slave
device (Logic Express in this case) to a new position, without implicitly starting
playback. This is useful when in slow shuttle or single frame advance modes with video
machines, because the slave device is perfectly located, without being in playback
mode.
MIDI Sync Preferences Button
The MIDI Sync Preferences button opens the Sync tab of the MIDI preferences (see
“MIDI Preferences” on page 987).
Unitor
The Unitor tab of the Synchronization project settings is used to set the major
synchronization parameters for the Unitor8 MIDI interface.
SMPTE Mode
You can instruct the Unitor8 to read or write SMPTE. You must switch from Read (the
default) to Generate, and set the frame rate and SMPTE start time in the General tab
(top Bar Position row).
Click the Refresh checkbox to enable refresh mode, where fresh time code is
generated—in sync with received time code. 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 cannot directly copy LTC without a considerable loss of quality. When copying
entire multitrack tapes, you should patch all tracks directly, but refresh the time code
track via the Unitor8.
Note: You should only use refresh mode if you are copying time code.
