Hydrogen is already a JACK Timebase Master and Slave. However, a quick glance
suggests it does not emit BBT information when acting as a Master, and does not
understand it when acting as a slave - i might be running a slightly outdated
If Hydrogen could be extended to produce (should be doable) and understand
(harder, but should be doable) JACK BBT information, the MIDI stuff could be
implemented as a separate JACK application that is not directly tied to
Looks like Gabriel's http://www.teuton.org/~gabriel/jack_midi_clock/ already
implements one side of such a bridge.
Such a solution would certainly be more complex, but also more flexible
compared to building this into hydrogen completely.
