Cwejman MMF-1

The Cwejman MMF-1 is a multi-mode filter module designed for use in Eurorack modular synthesizers. It was designed by Swedish synthesizer designer Cwejman and is one of the most popular filter modules in the Eurorack format. It is a four-pole filter with two independent filter sections, each with its own frequency and resonance controls. It also features a unique “morph” control which allows the user to blend between the two filter sections. The MMF-1 has been used by a variety of artists, including Aphex Twin, Autechre, and Squarepusher. It is known for its smooth, warm sound and its ability to create complex, evolving sounds.
