Octaves is a six band pulse-wave based analog additive oscillator. Pile up multiplications of your frequency to get a lo-fi-retro wall of squared sound! Octaves VCO features six doubled frequency pulses, or octaves, with common PWM and volume control for each of them.

There are six VCAs (one for each pulse) which let you modulate the volume of each octave. This can be done either manually or via CV. When a CV is patched to the Volume INs the manual controls become attenuators. On top of that, Octaves VCO has a multi-mix feature, this means that each octave is summed in cascade 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!
