I remember seeing some connection weirdness when I tested with pyjacksm,
but Torben said that's already fixed in another branch. It's called
"bpjack". I am currently unable to build it due to boost naming weirdness,
but depending on your distro you might have more luck. I think he said that
he changed the dbus protocol or something so that jsweeper will likely
not work.

I tried the master branch again and made two midi input connections.
Only one of those was restored. But I'm very glad to see that saving,
quitting and loading sessions seems to work with yoshimi, including
internal state, as it should. I'm reasonably sure what you experience is
a bug in pyjacksm master that might already be fixed in pyjacksm
"bpjack".

I'm very glad to see jack_session making headway.
Good work Cal :)
