I had this idea once to use aubio to implement a 'jackd transport time

sync source', i.e. retrieving the bpm and adjusting the beat so that

jackd-transport aware applications (like hydrogen) can run in sync with

external music.
The idea is to enable easy live use of drum machines, samplers and tempo

aware audio players in e.g. a DJ context. But this could also be used to

automatically create the Tap tempo for delays etc...
I even started to implement this, but some other coding got in the way...
