Sorry, you're right, the applications have to handle informations about
e.g. the actual song position by the sum of 1/16 notes, from the
starting point of a song. OT: Unfortunately Ardour as master, can sync
an Atari Cubase, but not as slave, while Rosegarden as master, can sync
an RX21, but not an Atari Cubase.

That is, what I was thinking of.
