Amazing filter!

Suuka, 14.07.2015
Currently I have 6 eurorack filters (mostly from Doepfer) and this is one of my favourite. It's a TB-303 filter clone, but it doesn't sound exactly the same (although I don't have a TB-303 to compare). It sounds very similar though, it has that characteristic 303 sound when resonance is set around middle or higher and it's great for making acid lines. With less resonance it's also useful for any other kind of synth sounds. It's cheaper than most eurorack filters, but it can easily compare with the best. Nice to have 3 CV inputs. Doepfer build quality is also perfect. Would definitely buy again.

Smooth and creamy sounding filter. Use it for more than just acidlines!

Zoë, 02.06.2013
I got this filter in order to make TB-303 style acidlines on my Doepfer A-100, and indeed it is pretty good at this. To my ears, it can't reproduce the full range of what the TB-303's filter can sound like, but it can sound very close to some of its finer moments. It can also sound quite different when it wants to. This probably says more about my patching abilities than the module itself, but some days I can get it to sound 303-like, and some days I can't. I'm sure some purists will point out the differences in how it sounds, but that's missing the point: it sounds GOOD when playing acidlines!

But this is a modular system, and using things in their intended ways really would be missing the point. Using other filters instead of this one, you can make acidlines that sound quite unlike the TB-303, which is also fun to do. Conversely, you can use the A-103 to make far more interesting sounds than just acidlines. It's a smooth, creamy sounding filter, and works well in all sorts of different contexts. For example, I once used it in conjunction with the A-127 module (emulating the PS-3300's triple resonance filter), and much to my surprise, the result sounded more like a Jew's harp than anything else. And that's one of the things I love about the A-100 in general: mixing and matching different parts of different synthesisers to make a Frankenstein style patch that by all rights ought to sound inconsistent, but in reality sounds unique and interesting. I'd recommend this filter, but more than that, I'd recommend that you remember to experiment with it, no matter what its origins!
