Cwejman’s MMF-1 is a tight, precision multi-mode filter that helped define the clean, controlled sound of early high-end Eurorack. Built in Sweden with Wowa Cwejman’s obsessive calibration, it delivers low-pass, band-pass, high-pass and notch responses with fast, musical resonance that stays stable even at high Q. Its crisp, low-noise character made it a favourite in detail-heavy electronic work, from clinical techno to sound design, offering everything from gentle tone shaping to sharp, rubbery resonance sweeps without drifting or smearing.
