Farbshaper is a classic West Coast analog waveshaper for Eurorack, designed to shape the overtones of an audio signal with two voltage controlled stages.

We have always been fascinated with analogue effects circuits, and we love the way their quirks and nonlinearities inspire us to find new sounds.

Farbshaper is based on a classic circuit that turns a ramp into a sine, and was historically used in function generators and oscillators. On any other signal it will add one or multiple wave folds.

The circuit produces opposite offsets internally, so the knob settings interact strongly and are fun to automate with CV.

This module is excellent to use as a non-linear shaper for acoustic and electronic sounds, ranging from gentle timbral transformation to colourful wavefolding.

It is part of our Farbfilter (colour filter) range of sound colouring modules, offering a wide sonic palette from lending subtle colour to rich timbre bending tones in 4HP.
