Peter,

Thank you kindly. I noticed you got some real heavyweights to do RealTracks, but I must tell you that Pat Martino, Kenny Barron and Ron Carter - of all the people - did a disappointing job. I was wondering if you'd be interested in some RealTracks from ... me! You can get them at the highly discounted price of ... FREE! My approach would be progession-based. As you know, there are two iconic progression in jazz: the blues, and rhythm changes. I would do these at various tempos and levels of complexity with varying instrumentation. At the outer limits, the blues can take advantage of every chord in the your "chord builder."

You may find this interesting: During my time away, I thought I had a solution to the 3x+1 conjecture (n -> n/2 if n even, n -> (3n+1)/2 if n odd - iterating, every 3x+1 sequence reaches 1). Yes, what every CS student gets as a programming exercise still remains unresolved. I know what a proof should look like, but the devil's in the details, as they say.

Let me know about those RealTracks.
