Frequently Asked Questions

About Me

I like music, especially making music. I listen to a lot of different stuff, but I like soul, jazz and fusion music most. I like to develop and experiment with tools to make music performance and improvisation on the spot more exciting. It is fun when unexpected musical things happen during a performance!

In recent years I developed the MIDI real-time Harmonizer, a tool for generating harmonized chords when playing a solo line. Inspired by the work of saxophonist Michael Brecker, I started to develop this tool to run on Mac and PC. Brecker played the Electronic Wind Instrument and used the Oberheim Xpander synth to generate random chords from an EWI solo line. Now you can accomplish the same thing with the MIDI real-time Harmonizer driving your own favourite (plugin) synths.
