Manta Improvisations:

The Manta is a excellent controller, invented and built by Jeff Snyder (see www.snyderphonics.com)

A first try with a "Rhythmicon"-Patch (January 2010): The Rhythmicon was invented by Stanley Cowell and Leon Theremin as a means to create complex rhythmic figures. I tried to replicate the instrument im MAX/MSP and added some features (transposition, sound effects).

The Beatmachine (January 2010): A MAX/MSP patcher with a lot of simple drum rhythms, that can be combined at will.

Some early sounds:

My first experiment with loops, concrète sounds in 1965:
