That's something I've been thinking about for quite a while now. I'm

planning to write a Jack Timebase Master which listens to an input port

analyzing the stream and tracking the beat. MIDI Clock output would be

next. My motivation is to sync seq24 & Co. to live drums. aubio comes

with a causal beat tracker but my first attempts with it were not very

promising. Causal beat tracking, however, is by no means trivial.

Especially if you do not know the kind of the input signal, e. g. drums

vs. a violin.
I did a little bit of state of the art research, so all I can provide

for now is a bunch of papers (and a project name FWIW).
Should you decide to start your own project on this, please get in touch

with me (LAC2007?).
