Kilpatrick Audio K3021 Master VCO

The Kilpatrick Audio K3021 is a single channel version of the K3020. Like its dual-channel sibling, the K3021 features triangle core VCO with waveshapers, allowing for even more timbral possibilities. Because of this, the K3021 is also optimal for LFO duties. The module’s waveshaping section boasts three distinct pulse outputs, which can be blended to produce even more complex waveforms.

K3021 Features

• Master VCO with on board precision power regulation
