I have a good knowledge of Max/MSP language, basically concerning sound synthesis, but I would like to move on to more automated stuff. I want to build a tempo analysis patch, so I ask to know more details about this topic.

Which is the best way to go? Is a simple amplitude thresholding going to do the job, or shall I use time/frequency domain techniques? If someone knows some reference points that would be great.

Finally I would like to know if developing an external for this job is a good idea, or is it better to program this in mxj???

Thanks for the suggestions, I was just looking at O.Pasquet's algorithm. It seems to do the job, but not very accurately though - probably timing issues in Max/MSP on a first glance.

Any suggestions for exploring things further in tempo analysis/tracking would be much appreciated.

I would like to suggest his very nice book: "Creating Music by Listening":

and a paper "Downbeat Prediction by Listening and Learning":

> T.Jehan's beat~. In fact, searching maxobjects.com for beat~ brings a 

also worth looking at analyzer~ which does some pretty good onset detection. (also looks at other details of the sound like brightness etc.)
