EFI is an analog multi-mode filter that draws inspiration from the iconic KORG MS-20 filter, refined to seamlessly fit within a compact 4 HP module. Celebrated as one of our top-performing modules, EFI stands as an essential addition to smaller modular setups, allowing you to save valuable HP without compromising on functionality.

Description / Manual

The front panel features a switch for easy toggling between Low Pass and High Pass Modes. Alongside, you'll find two CV inputs, each equipped with its own attenuator for precise control.

Experience the potential for self-oscillation with the Resonance, while a third mode can be accessed via a back-panel jumper. In this mode, the Resonance swiftly overdrives in Low Pass Mode, producing captivating liquid-like overtones.

The Module is built and assembled in germany and comes ready installed with the newest firmware.
