CEM3340 VCO with Waveform Mixing and Two Sub-Oscillators

HONEYEATER is a classic analog VCO with two sub-oscillators and mixable waveforms. It uses the famous CEM3340 "Curtis Oscillator“ precision VCO chip, that is also being used in fabled synths like the Sequential Pro-1 and OB-xa. Compared to other CEM3340 VCOs this module was especially made for live usage. The Coarse and Fine Tune potentiometer are located on the lower part of the module in form of small trimmer potentiometers. Having set these in tune, you won´t have to tweak those too often. On the top part you will find easy to reach waveform mixing potentiometers. Taking the output from the Out jack you can create your waveform from the sources Triangle and Sawtooth (alternatively via switch), Pulse and Noise. Additionally there are two Sub-octaves available that can be added to the output signal by using the Sub potentiometer. Sub-octaves may be activated using the dedicated switches.

Of course HONEYEATER also includes classic VCO features like Pulse Width Modulation (manually and via CV), Frequency Modulation (exponentional or linear alternatively via switch) and Hard or Soft Sync (changeable via jumper on the back).

This module is your best companion for rich sounding analog synth sounds in a low HP format.
