Ardour works well both as MTC master (as you did) and as MTC slave provided that
you use a low latency setting in jack. With ardour as MTC masterm, setting
latency to more than 10 msec makes many MTC slaves confused (too much jitter in
the MTC code from ardour). This jitter problem is not present with ardour as
However there is currently a bug that makes ardour "late" by an amount depending
on the latency setting (happens both as slave and master). With latence > 20
msec this becomes quite audible. This will be fixed though.
Bottom line, set jack latency low if you want to use MTC.
