qjackctl will start at the bar position given by Bitwig.
If Bitwig starts at bar 50 then qjackctl will start at bar 50. If
Bitwig loops between bar 25 and 35, qjackctl will do the same.
However, the time value in qjackctl will always increment whereas when
Bitwig loops, it will reset at the time value for bar 25.
At least this shows that the bar information is received correctly.
Then, I launch Mixbus. With Mixbus running, qjackctl seems to be
confused and not knwoing from which software it should get the bar
information as MB starts from 0 and Bitwig from at 25. MB does not get
the bar information like qjackctl did eg. it will not jump at 25. It
will start rolling at 0 when Bitwig starts.
Moreover, after closing Mixbus, qjackctl is not able to behave as
before showing the bar information from Bitwig. It will only show a
series of dashes instead while rolling along with Bitwig. Restarting
qjackctl did not make it behave like described above.
