Synth maker Waldorf revealed the 2-pole Analog Filter in the USA at the NAMM show. Now, they’re coming home to Germany with more details.

The emphasis here is making a filter for everyone: producers and synthesists, yes, but also DJs and guitarists. We already know guitarists like having access to this stuff if it can be playable (see KOMA, Moog), and if Waldorf can sell DJs a buttery filter instead of the awful stuff you get on many DJ mixers, they may be doing the world a public service.

The hardware has an all-analog filter path, which makes sense for a filter, using Waldorf’s own multimode filter design. (Waldorf has a track record here, with the 4-Pole, X-Pole, AFB16, Q+, Wave, and Pulse.) To that, they’ve added modulation (LFO, envelope follower, or external signal), and a lot of goodies that let you do more with the sound.

To keep this from just being a boring filter, there’s a Rectifier and overdrive after the filter; as you hear in the video, you can make some extreme-squelchy sounds, making this as much an effect as a run-of-the-mill filter.

And playability/performance options are what might really justify buying this as dedicated gear. There’s a Trigger button so you can “play” the result, true bypass, CV input for those with other analog gear, foot pedal controls for both the filter and envelope follower.

“Funk up your guitar licks.” Or lick up your guitar funk, perhaps. In any case, crank up the modulation and you have some pretty wild sounds.

It’s all mono, but you can “cascade to stereo” if you really want to buy two. I could see this box in a rig with gear from someone like KOMA; I’ll be in the booth with them this week, so maybe we can borrow a Waldorf and try mixing all this stuff together.

Availability: this month.
Pricing is 229€ (should see a bit lower than that in America).

    i don’t think this video does this product justice. i understand they are trying to target guitar players who want to jump into the EDM craze…which IMHO is on it’s way out, being replaced by trap, twerk, and intelligent dance music. the 2-pole filter really does sound better than what is heard in this video.

    This video is so bad. What you see and what you hear is totally unrelated. I’m definitely interested, though, but i would never buy this because of this ad.

    I have been watching this out of the corner of my eye as I like the Waldorf filters – my interest was in integrating into my Eurorack, so I am a little disappointed that the CVs are Qtr inch (though I understand why). Peter, would you be able to comment on how this might integrate into the Eurorack standard? Is it possible to use 1/8 to 1/4 adapters for voltage? Any insight (from Peter or anyone else) would be of interest.

    • Simon

      A simple adapter will do it. CV doesn’t care about the shape of the connectors.

      Yup, Simon is correct. I’ve got a Expert Sleepers ES-3 that I use to control my 1975 Minimoog and Moogerfooger pedals amongst other things. I use mono minijacks from the ES-3 and then have 1/8″ mono to 1/4″ mono adapters on the Moogerfooger side. Works great! Pretty much makes the stuff into software controllable external hardware plugins.

      The only caveat is that you always want to make sure that whichever device you are controlling can handle the amount of voltage you’re putting out. Some systems either put out quite high voltage, or are quite sensitive to high voltage coming in.

    Oh man – that guitarist needs a chromatic tuner more than he needs a filter

  • Downpressor

    That video pretty much had a reverse effect on me, after seeing it I want the product less than I did before seeing it.
