TXL sync issues over multiple flows

Hello all!

I’m using TXL timecode to sync up Logic with Dorico, and trying to use different flows for separate short cues on a single clip (thank you so much to @gdball for this suggestion!).

However, there appears to be some drift in the timecode sync over various flows. I have triple-checked my settings on TXL, Logic, and Dorico, and all seem to be correct (timecode start 01:00:00:00 on all, same framerate in Logic and TXL). I have also tested to see if it was just regular drift, but if I use a single flow, the timecode remains accurate, which seems to suggest it’s a flows issue. I currently have my flow settings to play directly one after the other, which would seem to be the optimum setting…

Any ideas on what’s going wrong?

EDIT: I’ve just double-checked, and TXL is always displaying the same timecode as Logic - it appears that the issue is between TXL and the various flows - i.e. the timecode staff does not match the timecode which TXL has…
