SERRA generates a fully controllable 4 segment function (Attack, Decay, Sustain, Release) that can be adjusted in time with its own sliders and external CV inputs.

Tweak and modulate shapes until they fit your taste thanks to its built-in Attenuverter & Offset controls.

Tweak it further.

We’re always thinking about how to get more out of our modules, so we decided to make these built-in Attenuverter & Offset feature applicable to an external signal if connected to the SIG input, and then extracted via the OUT output.

Wide range.

As fast as 1 millisecond and as slow as 40 seconds. You can even improve this range by applying external CV to the selected stage.

Clear layout.

Accessible and comfortable to use, the controls are easy to handle and you can always see the envelope state through the built-in LEDs.
