Bummer, no plugins running. Would have been nice to
have an explanation.

I haven't had time to think about this but I know the
dates where it occured for the first time and can
locate the Ardour update posting that corresponds with
the dates. It was the beginning of a serious round of
MTC changes. Probably useless to try thinking about it
that way. I guess if Josh, Doug and I are seeing it
one of us will gather some useful info.
