its been like this for years now.

i dont think that is correct.
seq24 does not work without a timebase master.
(either it must be the timebase master itself, or ardour for example
must be running. seq24 is not calculating the beat information based
on transport frames, which are the only transport information available,
without a master.)

yes. but without a timebase master on the slave machine seq24 hangs.
even when transport is running.

are you one of the new devs ?
if what i say is not clear to you i will provide a patch.
but dont have the time now.
So this has to wait until the weekend i guess.
