The successor of the dignified MMF-1 bases on its capabilities as a ultra-clean multi-mode filter with seven selectable filter types and two slopes, expanding it by voltage controllable saturation with compression and second harmonic emphasis, then a MIX parameter for fine timbre tuning between original and processed distorted sound or a VCA at the output. The module combines the clear sound of the old MMF-1 with the saturated timbre of the MMF-6.
We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)
The MMF-1S offers seven switchable filter types and for some of them two selectable slopes. In combination this equals eleven different filter:
- low pass with -12 or -24dB per octave
- high pass with -12 or -24dB per octave
- bandpass with -6 or -12dB per octave
- three dual band passes: dual peak, upper peak, lower peak
- single notch (in -12dB setting), dual notch (in -24dB setting)
The show stopper is that in the dual modes the distance between the two resonance peaks can be adjusted with the voltage controllable parameter SPACING which is great for creating vocal sounds!
The two audio inputs both have individual level controls; cutoff and resonance of course are voltage controllable. The Q PEAK MODE switch determines whether the resonance starts to oscillate in its maximal setting or not.
The filtered signal is emitted at the MMF socket.
The second part of the module is comprised of a saturation stage which distorts the signal in a nonlinear fashion. Besides the voltage controllable Saturation parameter which sets the amount of saturation, there's a 2ND HARM control emphasizingthe second order harmonics.
A compressor with three selectable compression rations (1:1, 3:1 and 20:1) is integrated in the saturation stage as well.
The saturated signal is available at the MIX VCA socket, yet the result depends on the VCA/MIX switch and the MIX control:
In switch position "MIX" the MIX parameter blends between the original signal (AUDIO 1&2) and thefiltered/saturated result (SAT). This can be voltage controlled via the "CV VCA-MIX" socket.
In switch position "VCA" the MIX control has no effect and the CV input "VCA-MIX" turns into the VCA's CV input.

The history of Cwejman goes back to the 1970s with a bespoke fully analog synthesizer called the Synthra. After a long hiatus due to the heyday of digital synths, they returned in 1998 seeing that the interest in analog modular synths was catching up. Ever since, Cwejman has been a synonym of uncompromising engineering aimed to provide outstanding sound quality.
