[LAU] Synchronization of audio with MIDI file

[Studio Channing]

that is a good find and maybe answers a thread from earlier today 
"software communication with acoustic instruments"

there were some discussions about this recently in our project studio: 
making a linux application, configured with an idealized MIDI drum 
score, that listens via MIDI to electronic drums (or acoustic kit with 
triggers) and tries to calculate the "real-time" tempo based on the 
incoming drum notes - and then updating jack transport with fine-grained 
tempo changes - in theory then any jack transport-aware looper or 
sequencer could play along with the band

but we never got beyond the "talk over beers" stage and were unsure if 
it would work: how would sequencers react to continuous tempo changes? 
on a deeper level: how hard is the calculation of tempo when you have an 
"ideal" score vs noisy MIDI data coming from the drums? I see now that 
IRCAM have spent decades researching the "score following" problem:

http://repmus.ircam.fr/antescofo/videos#score-following-history-in-video

(also I notice their sample human player is not a drunk rock and roll 
drummer... and thus that part might be a bit "idealized" as well..)

so we would also be curious about experience with this or other similar 
software. it also would be interesting if there's any open-source code 
that could be "borrowed" for a jack-centric system as described above..
