JLCooper PPS-2 Remote for Mac OS X - Manual (Page 8)

Sync Type
The PPS-2 can work with three different synchronization types, MTC (MIDI Time Code)
Smart FSK (Frequency Shift Keying) and DTL (Direct Time Lock). MTC and DTL are
protocols for converting SMPTE time code into MIDI information that music software
and hardware can synchronize to. Neither of these settings affect how the PPS-2 stripes
SMPTE.
When the PPS-2 is in FSK mode, it doesn’t stripe a tape with SMPTE. Instead it stripes
the tape with a tone. When the tape is played back, the PPS-2 converts the tone into
MIDI Song Position Pointer and MIDI Clock messages. Some older music software and
hardware use this method of syncing to tape.
Since frame rate has no meaning when FSK is being used, the Frame Rate controls are
disabled when you choose FSK. They will be re-enabled when you choose either MTC
or DTL.
DTL and FSK are rarely used anymore, and you will probably keep the Sync Type set to
MTC.
The Sync Type setting overrides the Default Sync Type set in the Preferences dialog.
Changes to the Sync Type setting are undoable and redoable.
