Cwejman MMF-2


The module Cwejman MMF-2 is a stereo multimode filter. It can be used as a true stereo filter or like two independent filters. Besides the cwejman´esque clean sound the filter has a switchable saturation stage allowing you for creating distorted wild sounds. Lots of filter types, voltage controlled parameters and also the dry/wet parameter make this filter a complex tool for sound processing.

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 two independent filters LEFT and RIGHT are 4-pole multimode filters i.e. they have a slope of 24dB/octave. Per filter there are individual outputs for lowpass, bandpass and highpass.

The main outputs "left" and "right" are switchable between six filter types: lowpass; low-/bandpass; bandpass; band-/highpass and notch. Besides that it is possible to bypass the filter in the seventh switch position.

The cutoff frequency of both filters can be controlled simultaneously with the "master cutoff" potentiometer. The resonance control of the left filter can be used as master for the resonance of the right filter by the flick of a switch.

The saturation stage hast three operating modes: hard, soft and off. In hard mode the even harmonics are dominant, in soft mode the odd harmonics. Saturation can be set pre- or post-filter with the according switch. Wich filter bypass activated you can still saturate the signal ans thus use the MMF-2 as an independent distortion.

The MIX parameter controls manually and with CV the relationship between unprocessed signal and the filtered and/or saturated signal of the main outputs. The individual outputs won´t be affected by the mix parameter!


We currently do not accept pre-orders for Cwejman modules. For some products, there are waiting lists with pre-orders from the years 2013 to 2017, which are being processed as a matter of priority.
If you’d like to be informed as soon as this module is back in stock, please activate the availability notification via e-mail.
Please note: The number of Cwejman modules is always limited and much lower than the number of interested parties. Therefore, we recommend to order IMMEDIATELY and ONLINE if a Cwejman product becomes available. Enquiries via e-mail or telephone are usually not fast enough.
If the demand is higher than the supply, unfulfillable pre-orders will be deleted. In this case you’ll receive an e-mail. (Pre-orders on the waiting lists mentioned above are excluded from this policy.)


Audio inputs L+R; left is normalized to right.
