Impressions of the Cwejman MMF-2 stereo multi-mode filter.
The MMF-2 came out this summer and quickly sold out. Having spent some time with one, it's easy to understand why. It offers a wealth of possibilities and sounds great. Have a listen:

The MMF-2 can be used to process mono or stereo signals. The filters can be run in parallel, or if patched, in series. It features two types of saturation and a dry/ wet mix. For a full description, see the MMF-2 product page linked above.
The MMF-2 shares much in common with the MMF-6. It's confident, bold and, to my taste, more musical than its single-sibling. It FMs beautifully and, when oscillating with some saturation, can be used for plucked/ percussive sounds or aggressive basslines. It can also be self-patched to make crazy, chaotic noise. It really comes alive when using the mix feature.
Here are some thoughts that cropped up in use: the initial frequencies of the left and right channels need to be manually balanced in stereo patches. You can't sweep the entire frequency range with the master as the L&R cutoff pots are offsets. Inter-channel CV normalization and attenu-verters would be useful e.g. in a LP/ HP configuration. The filter slopes might be too steep for some external audio processing tasks. Saturation is either on or off, but the amount is determined by the input level. I would have liked an input VCA but, as Wowa told me, the MMF-2 is already 'a beast', both in terms of size and stereo circuitry.
The MMF-2 can be clean or brutal, used to transform mono or stereo signals or even as a dual voice module. Look out for the next run.
Thanks to Wowa for answering my questions and to Schneidersbuero for the loan.
