Befaco - Octaves VCO

video upload by Befacosynth

"A harsh and funky take of an additive Oscillator.
Pile up multiplications of your frequency to get a lo-fi-retro wall of squared sound!
You get six doubled frequency pulses, or octaves, with common PWM and volume control for each of them.
The output of each is cascaded to the next one, so you can either have one output with all frequencies or break the chain and get several sums and modulate each independently!"

A harsh & funky take on an additive oscillator // Octaves VCO from Befaco

"Here we have what Befaco say is "a harsh and funky take on an additive oscillator" as it has individual harmonics or partials and VCAs to modulate them. However the idea of harmonics here is replaced with 6 octaves of square waves. It's an analog design with a triangle core oscillator that through frequency doublers give 6 octaves to work with, each turned into squares that respond to PWM. An onboard mixer allows for blending these squares, you can break out into new tones with self patching, or make multi-layered wide frequency spanning voices from the individual outs."
