Feigen is a quasi-chaotic voltage source. The signals produced by Feigen have very interesting properties than can be used for modulation or melody generation.
On it’s core lies the Logistic Map equation which is capable of producing periodic and chaotic patterns depending on it’s settings. Additionally, the generated sequences can be controlled by selecting the initial state (the Root) and resetting the module.
Feigen was back-ported from VCV Rack (software) to Eurorack.
