LTC QuickLok
Allows your Express interface to sync to SMPTE time code 
received on its SMPTE input jack and convert it to MIDI 
Time Code to be sent to the computer and other devices. 
This mode provides fast lockup to LTC, but it doesn’t 
provide as many other features as LTC mode (above).
Frame Rate menu
The Frame rate menu lets you choose the overall time base 
and time code frame rate for your MOTU interface. For a 
complete explanation of SMPTE frame rates, see “Frame 
rates” on page 83.

The Sync tab has the following status indicators and 
options:
