what joachim's saying is true - if i'm reading what he means correctly.
noah - i think he means that syncing between, say, ardour/jack/hydrogen
should enable dynamic (?) tempos - that is, if you set a change in tempo
in the ardour tempo strip at the 12th bar from 80 > 90 bpm, then
hydrogen should folow that tempo change accordingly ... i'm not sure if
this is what the current setup is supposed to do but just can't manage,
or if it's a feature that isn't possible yet with jack ...

i don't know - i find things like tempo/measure/time signature really
confusing. it does the same thing to my brain that the start and end of
daylight savings time does.
