Explorations around a schematic found among old papers of mysterious origin, suspiciously similar to a datasheet sq/tri oscillator. All that was needed was to connect the dots.
A slew limiter smoothes out how quickly incoming voltage can change, limiting it to a fixed v/sec. slope. Since time and frequency are intrinsically linked, this acts as a steep, somewhat distorted low pass filter.
When it resonates, these fixed slopes become triangle wave oscillations, giving 20% more its unique sound. Input signals can overwhelm this oscillation, making for pseudo-wavefolding and synthetic distortion artifacts.
jfet clipping, sub and upper octaves, envelope follower, low pass gate; impressions, ideas, pleasures and pains.
When the envelope goes to FEED, the average feedback is lowered slightly, loud playing will bring it back up. As loud inputs also fight the oscillations, interesting swashes of noise arise as your notes decay.
Two flip-flop based clock dividers, giving sub-octave and sub≠ sub-octave effects. It is only heard when BLEND is up somewhat. The sub octave is summed through diodes, giving it a characteristic 75% pulse.
Play with INPUT. Interactions become intuitive.
