Hi Eexee, Farkas and Toodee,

Eexee: Other than the already mentioned filters by Farkas and Toodee, the Doepfer A-124 Wasp filter is one I love, it can go quite bananas without becoming irritating like a TouellSkouarn filter that mainly just screams. So if you are looking for a screaming filter go for a TouellSkouarn filter, they have a few, the Kala Goañv isn't actually that bad and kind of okay-ish.

Patching Panda, the Vibrazum comes to mind, still discovering that one myself, not sure what to think of it but good enough to consider it. If you like more something smooth then I can recommend the Instruō - Tràigh filter, pretty decent and not rough at all, rather the opposite more like to smoothen your sound or to give it just that extra touch. A bit like the Polivok filter that Farkas mentioned I guess.

If you look more for a Roland style of filter then go shopping at Frequency Central, the State 700 Mk 2 filter for example. Not an exact 100% filter as such however if you are interested in a resonator then the Mutable Instruments - Rings is actually a quite fun "filter" (resonator is a better description) and is recommendable.

Naturally Doepfer has about a half thousand of filters or something like that, not going to name them all here however one or two that might be a bit special and to be considered are the A-108 is a transistor Moog ladder filter with 6, 12, 24 and 48 dB/octave steep slopes that can provide you interesting options. The other less obvious one is the A-128 fixed bank filter. I use that one sometimes to get rid of certain irritating sounds in my music that I can't get rid of in another way (or too lazy too figure out what's causing the irritation). It doesn't do wonders but it can make irritating sounds more smooth or less harsh and of course it can be used for many other purposes as well.

Hopefully this gives you some ideas. Good luck with the search for another nice filter :-) As Toodee mentioned, I indeed can seriously recommend the Erica Synths - Black Dual VCF, it's a great filter with some really nice features and possibilities, check out my demo here:

Mutable Instruments - Rings can be heard here:

And the Make Noise QPAS here (and later on in that demo again the ES - Black Dual VCF):

Last but not least if you are into quadrophonic music or just playing chords, then I can recommend Doepfer A-105-4, here is a demo of it:

Farkas: Interesting description of the Erica Synths' Polivok filter but I do think I can agree here with you how you described it. For myself I still need to more understand this filter, it seems I can't get the max out of it, or perhaps I put my expectations too high and want to get more out of it than it's possible ;-)

Toodee: He, he, yes that Black Dual VCF is still a fantastic filter, thanks for recommending it :-) I still love this filter a lot, together with my Doepfer A-124 Wasp filter and Doepfer A-106 SEM filter the best ones I have!

All: Enjoy the pleasure of playing around with filters and kind regards, Garfield.
