ADDAC701 VCO

Analog voltage-controlled oscillator module

The ADDAC701 is a fully analog voltage-controlled oscillator for Eurorack that produces four simultaneous waveform outputs - sine, triangle, sawtooth, and rectangular (pulse) - along with a mix section for blending them. It tracks 1V per octave pitch and has a linear FM input with adjustable depth, while the rectangular wave offers voltage control over its pulse width. The current REV2 version uses a CEM3340-based core for pitch tracking that stays stable across seven octaves.
