02 Design principles
Small surface area
Focused software with fewer dependencies, fewer failure points, and less between you and the work.
Atmosphere with purpose
Tools with a point of view: restrained enough to learn quickly, deep enough to make something distinctly yours.
Soft Voltage Studio
Software can be calm and still have teeth.
We make compact digital instruments for writers, sound-makers, and curious people who prefer useful objects over sprawling platforms.
