Frap Tools Fumana is a filter module for modular synthesizers in Eurorack format. The module has two filter banks, each with 16 bandpasses per channel. The first channel is designed for modulator signals and has one envelope follower per band. The second channel is for processing audio material and has a VCA. It is possible to feed even and odd-numbered bands independently of each other with audio signals. An unvoiced input has been implemented for vocoder effects. There are also tilt and parametric scanning functions.
