Analog-style sub-octave + octave-up, plus a microtonal quarter-tone shimmer voice.

An analog-voiced octaver: a flip-flop sub-octave plus a rectifier octave-up, blended with dry via Up, Sub and Dry controls. Monophonic tracking — clean and singing on single notes, gnarlier on chords.

It also hides something no vintage octaver did: a pitch-tracked microtonal SHIMMER voice that shifts in quarter-tone (24-TET) intervals — quarter-steps up or down, neutral 2nds, 3rds and 6ths, or an octave-and-a-quarter — for shimmering, slightly-alien lead tones that sit between the notes on the fretboard. Light on CPU; runs on every target including 32-bit Pi.
