Music systems like arranging, notes, and tunings are the earliest tools we have for controlling timbre. About 20 years ago, it occurred to me that one day, there would be new ways to control timbre without the need for traditional music systems.

With this in mind, I started developing some early models using various types of synthesizers that didn't work too well due to the limitations of MIDI and low-powered machines. Years later, I was able to resolve these limitations using USB, Softsynths, and fast computers to devise what I call the "6X6 Ultramegaphonic Interactive Frequency Modulator." A system of 6, 6 Operator FM Synthesizers that are controlled in real-time with custom-made interfaces. Nothing is predetermined in this system. There are no keys, samples, loops, recordings, or sequences. When I turn it on, and start turning knobs. Things can go in any direction at any time. It's a bit like trying to drive an avalanche, as you have a lot of power but no control over the destination.

Listen to what music-less timbre can sound like. The following tracks were all created by manipulating the waveforms and envelopes of 36 oscillators in real-time directly to the mixes you hear.


released December 2, 2021

This album originally released in 2013 is available again here with new 24-bit remastered recordings and additional tracks.

These compositions are dedicated to John Chowning who has greatly inspired me to explore the vast sonic worlds of FM Synthesis.

Many thanks to my friend Eddy Sonic who keeps reminding me what sound is really all about.
