is there a program i could use (similar to beat detective) where i can track a guitar performance and create a tempo map accordingly?
I`m recording a folk guitarist and i want to keep his variying tempo fluctuations. I have sequenced drums that i want to add to the guitar, but i want to make sure they are in sync.

I'm currently in Los Angeles where my daughter's band is recording in a Pro Tools environment.

I'm seriously impressed with the Beat Detective function.

Question: is there something similar for Sonar?
