Basically: Let a drum or midi track of muse use Hydrogen's Midi-In as 
O-Port. The MIDI connections are established with muse's MIDI port 
configuration and best viewed with kaconnect. Both apps use jack as 
audio driver. The audio connections of muse and hydrogen to alsa_pcm 
playback channel(s) are automagically established via jack; but you may 
check them with qjackconnect anyway.
Actually, sometimes hydrogen cannot connect to jack. It seems like I 
have to shutdown qjackconnect before....
I'm afraid that is nothing new to you. But if you use ardour, all other 
requirements like ALSA or jack are supposed to work.

I'm using beta-c right now, and I got some sessions, that deserve to get 
migrated through ardour's still evolving persistence concepts.

I reported the behaviour to ardour-dev list.

I'd suggest to eliminate, shutdown or un-load drivers, midi interfaces, 
OSS emulation or even hardware, that are not necessarily need for 
testing a specific MIDI setup.
And: Sound seems to require lots of restarting/rebooting apps, OSs, 
muses, ardours etc.pp.

Agreed, but I want it now :)

P.S.: I temporarily added MMC DEFERRED PLAY to ardours MMC cmds, muse 
even rolls now with ardour, but still refuses to sync to ardours MTC :(
