Hey, Rama!

I just saw a very impressive thing by Ed Large (a neuro-science guy from UCONN). He models neuron oscillations with coupled nonlinear equations and with this he gets really nice spikes at the pulse tempo even with signals that don't have any onsets on the beat.

He said the model will be available in a month or so and the paper is still under review. The other thing is that there is a training layer (also neuro-model motivated) that you have to warm the thing up with, but my impression is that you only have to do this once and then it is ready to go. It's worth keeping an eye on for beat tracking solutions.

Hi Peiman,

maybe check out antescofo~, there’s a pd version here: http://forumnet.ircam.fr/shop/en/forumnet/44-antescofo.html

I’m sure there are ways to patch this as well, but antescofo~ makes use of some nice HMM tricks to anticipate when you’re going to play next.

best,
Rama

Hello everyone,

I am in serious need of advice! Here is what I need:

I need to compare a click-track with the input from a live midi sequence (played on a midi drum pad) and slow down or speed up the click track to match the tempo of the live midi input. So I need to generate a speed factor that will change dynamically to keep the click track in sync with the live sequence. The problem is that the two need to stay in phase so a simple tempo follower won't work. 

It's more complex that I'd initially though it would be. Any suggestions? 

Many thanks in advance
Peiman
