Noise Engineering Variatic Basicus

Six momentary gate switches in 8HP

8 HP Eurorack module

Variatic Basicus is a straightforward gate control surface: six debounced momentary switches, each with a dedicated output jack and LED indicator. Press a switch and a gate goes high at the corresponding output; release it and the gate drops. The module requires no clock, no programming, and no menu-diving. It is designed for hands-on, real-time triggering of envelopes, drum voices, sample players, or any gate-responsive module in your rack. The debounced switches ensure clean, reliable triggers without double-firing.
