... the Black Elements features a classical, subtractive signal flow. A closer look then reveals some cool oddities like unconventional filter slopes, extensively equipped modulators, a band echo simulation and a spring reverb. The Elements EL-2 features a completely discrete circuit design. Its sound is creamy and fat at the same time. Thanks to NOS components, the instrument has a nice vintage vibe. Compared to its predecessor, the EL-2 offers some very useful additions. – Especially its three oscillators have been extended considerably.
The outstanding synth has 3 VCOs, a tape echo simulator, a filter/resonator combination, a spring reverb, and really large modulation potentiomenters. Also the sound is huge but what really stands out (optically) is the golden touch keyboard with quick response.
The Elements has a CV and gate input socklet pair, several CV inputs, e.g. for separate VCO control, filter cutoff and for the VCA. A spring reverb line in/out socket is installed as well.
