that's a funny question.....

i tried like mad to built that into converter... but performing realtime beat recognition, or tracking the tempo fluctuations of a live audio source (say live drummer) was extremely complex to implement in a practical and predictable manner.... important if converter was to be useful for live use as a midi clock source....

so i got rid of the code for beat/tempo tracking and just left in the code to generate a fixed midi clock....

your application (dj or live beats / sync synth step sequencer to turntables) was exactly the application i was aiming for....

sorry man :(


(incidentally, to any programmers out there, the tempo tracking problem was related to the time between "hits" or drum peaks in the beat, and how quickly a dj or live drummer could change the tempo of the beat converter was tracking.... converter couldn't 'lock in' to the tempo quickly enough... seemingly easy thing to code in theory, but the reality is quite different... :wink:
