  ADDAC701 VCO

  Portugal

  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.

  2hp VCO

  United States

  The 2hp VCO is an analog voltage-controlled oscillator built around the reissued Curtis CEM3340 chip. It outputs triangle, sawtooth, and square waveforms simultaneously, with pulse-width modulation, linear FM, and hard sync. Accurate 1V/octave tracking across more than ten octaves suits both melodies and dramatic pitch sweeps.
