Behringer 121 Dual VCF 5-stars Reviews

Product delivers that Roland System 100 VCF precisely

If you're looking to bring a classic filter to life in your modern eurorack setup at minimal price, Behringer provides the way. Arguably as high quality or better than any offerings from Roland themselves, who have frankly ignored the Eurorack market at their own loss. Behringer is committed to reviving the classic Roland and Moog modular synthesizers of the 70s and making high quality, modern, careful recreations of all of their models and more.

Getting your hands on a real 121 Roland module in working condition from the 70s, provided you even have the right place to rack it safely, will cost you upwards of $1000 and not be different in any noticeable way except perhaps that single unit's own wear from 50 years of being on this earth.

Roland's own revival would be their, confusingly renamed "SYS-521" Eurorack module and frankly, the look and feel is less like the original, and it costs 5x as much as this Behringer unit. Save yourself the money - if this is the filter you want, go Behringer..

Great for the money

Great filter and eurorack audio mixer for the money. Just a bit noisy sometimes.

An excellent addition to your rack!

This VCF features 3x2 3.5mm inputs with attenuators and 3x2 modulation inputs with attenuators. It has 2x2 Outputs and a HPF with 3 modes (a la juno).

Yes the knobs are small and somwhat hard to reach when it is patched in, the sliders are small to but easier to reach and they all feel sturdy.

The sound quality of the filter is good, it has self oscillating capabilities. It has a rather fast and hard response, good for pinging and such. Over all it is a very good module given all you get. 2 separate filters with 3 modulation inputs each. The only downside is that it's hard to tweak and reach in between cables. But I can live with that.

Very clean sounding jup8 style filter, times two. The only real negative is that the input levels are low biased, it takes effort to overdrive this thing, and consequently for this filter topology in general if you increase resonance the output level tends to lower significantly. That said, I love it, 3 sig inputs with attenuation, 3 control inputs with attenuation. 2 outputs. Yesss! Long time ago I found a system 100 samplepack and mesmerized by the sweet, pristine, deep and liquid cutting nature of this filter. So yeah this thing does not dissappoint, even if it contained one filter its worth the money, but hey you get two. Selfoscillation occurs kind of abruptly but I don't mind. The selfoscilation is always very controlled and sweet. The whole ergonomics is very natural, compact and to the point, as in a total joy to use. As it's all surface mounted so modding seems unappealing although I might get into bypassing some input resistors to crank up the gain.

Fantastic Value and Roland Sound

I wasn't sure about this when I ordered it, but after a few days in my rack, I love it, sounds just like vintage Roland gear, very solid build quality, and great sound. Buy one or two you will not regret it

fat filtering fun

I just sent the Neutrons VCO through one of the filters,

worked great . fat sounding filters with drive

looks nice with the red leds

switches and knobs feel well made,

the knobs are a little small, but not a deal breaker.

a happy buyer

creamy and smooth dual filter for half the price of most filters

Can't say how faithful a reproduction of the original Roland module this is, i've never had the pleasure to play with one, but it is an amazing sounding filter. sorry, an amazing sounding PAIR OF FILTERS.

Having 3 inputs, 3 attenuators and 2 outputs per filter means you also need less utilities in your rack.

If one of the CV's had been dedicated to the resonance it would have been perfect, but as it stands is still pretty much great.
