The LANC MIDI Time code generator is a simple, lost-cost way to synchronise MIDI and Music sequencers to video playback and recording. The generator reads the Time Code information using the LANC (Control-L) protocol found on Sony (and some other manufacture’s such as Canon) video equipment and converts it into MIDI Time Code (MTC).
The LANC MTC Generator
automatically senses the type of frame format being used. However,
the difference between 30 fps and 30 drop frame can only be detected on
the minute transition when the minute is not exactly divisible by 10[*].
For this reason once the frame format has been detected it is stored and
used as the default next time the cable is used.
The Cable connects into the MIDI IN port of the synchronisation slave (e.g. hardware or software sequencer) and the 2.5mm jack connector to the video device LANC/Control-L port.

If
the cable is used with a different frame format system it is recommended
that the cable is connected to the video source and the video allowed to
play over a couple of minute transitions. (Usually the
Synchronisation device or software will show the type of MTC being
received – this can be used to confirm that the correct frame format has
been detected).
