This is something I'm interested in doing, but I've not looked into
whether it's possible or what would be necessary -- using Jack 2 with
multiple interfaces.

I'd like to record drums with a track per mic, but on an 8-piece set
with a hi-hat mic and two overheads, that's a lot of inputs.  (I have a
mixer that can provide mic preamps and line level direct outs per
channel, so preamps aren't the problem, just quantity of analog ins on
the computer side.)  My Multiface-II only has eight analog inputs, but I
also have a Babyface Pro which could possibly offer more.  Is there a
way I could use them both simultaneously with Jack 2?  Could that be
setup from preferences in QJackCtl somehow, or from some other frontend?
