Summary	0001631: When locking to MTC, if the MTC generator and Ardour are not locked to the same ref, they drift apart.
Description	When locking to MTC, if the MTC generator and Ardour are not locked to the same ref, they drift apart. This in itself is not the problem, this could be argued to be expected. The problem as I see it is that Ardour does not give any indication that this is happening. Over a long period the difference between the incoming MTC and Ardours timeline could be significant. There are possibly two solutions. 1. Ardour slews to track the incoming MTC. 2. Ardour indicates that the timeline and incoming MTC are out of sync. This could be indicated by some flashing indicator and/or a clock to show the difference between the two.

related to	0001608	closed		Lock indication when received MTC is good and being locked to.
related to	0001775	feedback		The config option "timecode-source-is-synced" from the ardour.rc file should be exposed to the user as a configurable option.
