Ian Fritz


Ian Fritz has designed tons of synth circuits, many of which are beloved in the synth DIY community, for Eurorack, and MOTM formats and more.


A word from Ian's website:

"After many years of neglect, analog synthesis is once again popular.
Some of my newly developed and improved synthesizer modules are presented here, with special emphasis on new types of modules not previously available.

Chaos science is now a large and important mathematical and scientific discipline. Chaotic processes combine regular and irregular behavior, analogous in many respects to musical composition and natural sounds.
I present here some novel and unique electronic chaos circuits for analog synthesizer applications.

My custom synthesizer system has special modules for use with wind controllers. A "wind controller" is a hybrid instrument that is "played" like a traditional musical wind instrument, but rather than producing musical sounds directly, it produces electrical signals that are used to control electronic-music sound generators.

Two different custom-designed wind controllers are described on these pages — an all-analog design for use with modular analog synthesizers and a MIDI controller for use with various commercial synthesizers and sound modules."
