This design has since evolved into the Auto-Step Synthesizer which is built with the same circuit.
This is a handmade synthesizer based on a stepped-tone generator. With a sweeping LFO it has an almost automated looping effect, as well as a low-pass filter that allows you to sweep the high-end in or out.
You have controls for LFO speed, frequency, pulse length, low-pass filter, and volume. The case is extremely tough die-cast aluminum.
With a 1/4″ output jack it is easy to connect to amps, effects or recording equipment. It is powered by an included 9volt battery.
This was built as a limited set of 3.
