Your top 2 indispensable Eurorack Filter modules |
  |
|
Following on a bit from a thread in MW, if you had to limit yourself to 2
Filter modules what would they be? (and please don't say Plan B-for obvious reasons!). I havent tried enough models to venture an opinion but I'm looking forward to an elby synthacon arriving! |

| well, don´t have a moduler system yet, but i love your avatar, i´ve got it framed at home, believe it or not! |

Off topic..
There are 3 filter designs that are vital for a modular system.
First there is the "standard" state variable filter .. like the dotcom Q107.
Then there is the Moog style transistor ladder filter and finally the fixed filter bank.
Trivia: The dotcom Q150 transistor ladder filter has a most brilliant output leveling feature.
I reckon the original question was probably which specific eurorack filter modules are worth buying and the answer is that I have no idea. 
IMO, as long as you get decent versions of each type then you should be fine. BTW, the fixed filter bank type is probably underrated these days. Too bad.

If I had to choose only 2 Euro filters, Id be going for the A-124 Wasp Filter and the A-121 Multi-mode Filter. The wasp because it is a great sounding filter (to my ears) and I'd be lost without it. The multi-mode because of it's utilitarian nature.

I agree that fixed filters in general are very underrated.

As others have written, consider a state-variable (aka "multi-mode") filter that includes LowPass, Highpass, and Bandpass outputs. Don't go with less than a 12db/8ve rolloff. You may prefer 24db/8ve which happens to be the rolloff for the Moog filter. But 12db per octave is not a lot different than 24db but 6db per octave is more of a tone control effect than a filter effect.
I agree that a Fixed Filter Bank is useful -- you could make a case for a FFB as your second filter though some people would opt for another Voltage Controlled Filter and then a FFB. I would suggest that one can use the FFB for refinement where as one might choose, say, a diode-ladder filter to get more blatant/unrefined effects (I'm in the process of building the Yusynth Diode-ladder which is a little "rougher" sounding than a transistor-ladder filter.)
My recommendation would be to start with a somewhat standard VCF as mentioned above, then add another VCF that has a more "exotic" quality, then consider a FFB as your third filter.
Also, consider a wave-shaper, too (I've built the CGS wave shaper). If you are interested in producing lots of varied timbres, a wave-shaper in combination with VCFs will offer many possibilities.

When I started building my little modular to expandmy voyager I opted for a Doepfer A-106-5 SEM and a Doepfer A-124 VCF5 Wasp Filter.
I have been told there are better SEM type filters but the Doepfer one was cheap and it sounds pretty good to me, though I am not an anlalog expert in any way!
The Wasp filter is really good as well, buzz buzz.
Both these filters have BP and LP/BP mix and I am happy with them.
I also got the A-136 Waveshaper, the idea being to place it between two filters, this module is a bit of a hand-full as the voltage output can very greatly, I am not sure if I would recommend one of these but I have not given it much time yet.
I also have a Dark Energy and the filter on it sounds great to me, these filters combined with the voyages are plenty enough for me!
Actually that is a bit of a lie, I quite want a Mateasonix R-52 and a Sherman Filter Bank would be nice.
Luckily I have run out of rack space (and real space) so I am saved at the moment
