So problem solved? Jonetsu needs to either have jackd not touch ALSA, or
use the seq interface, then configure Bitwig to use jack audio and ALSA
MIDI.

depends on whether or not bitwig uses the ALSA raw MIDI API. if it does, then JACK (and everything else) should not touch ALSA MIDI at all. If Bitwig uses the ALSA sequencer API, then things should be fine either way.
