u-he twangstrom public beta

 ·  Source: u-he


Esteemed German developer u-he is gearing up for a new release – a spring reverb plug-in. First demonstrated at this year’s SuperBooth, u-he’s Twangström is shaping up to be quite something. A spring reverb that you can easily dial in and blend into your production, rather than letting it inevitably take centre stage of your sound.


Currently in public beta testing, Twangström already looks accomplished and sounds well-polished, according to early feedback. At its heart, the plug-in is based on the spring reverb algorithm from the Bazille synthesiser. In u-he’s own words, they built on its foundation by physically modelling two additional reverb tanks (famous ones, at that) and adding an overdrive section, filters, an envelope and a mod matrix.

So rather than impulse responses, which is the more traditional and safe approach, Twangström is all about crunching maths and simulating the physical properties of springs while giving you full, real-time control over the process. It can get as complicated as you want it to be.

For example, the multi-mode filter can be routed pre- or post-reverb tank, while the envelope reacts to signals from inputs, outputs, and sidechain inputs. Add springs you can actually give a good shake to, and Twangström becomes a very interesting software toy. Certainly not another spring reverb to play beach rock with! Knowing u-he, the sound is already on point and finishing up the plug-in is likely a matter of incorporating feedback from the beta period. And kicking off 2019 with a new u-he release  sure sounds great to my ears!

Price and release date

Currently a free public beta, Twangström will be sold at a discounted price of EUR 49, down from a regular EUR 69. The promotional pricing will be valid until January 7, 2019 and the final version will see its release on the following day.

    What a great name for a spring reverb.

    What the hell is “beach rock”? I assume you mean “surf rock”?
