Full Synthesizer Voice

The “KOE Vactrol” which features our classic AtomoSynth vactrol-based 12db/oct Low and High pass filter. As always it is a full synthesizer voice in one module, this means it features all the basic submodules like an oscillator, low-frequency oscillator, filter, and envelope generator, these are internally pre-connected so it produces a classic synth sound with the minimum patching (only CV and gate signals), however, each submodule can be used individually thanks to its extensive patchbay allowing great flexibility, making it a great addition to your actual modular system or a perfect entry point to the world of modular synthesizers.
