Change is the only constant

Derivative R0 originally ran in December of 2021 as an exclusive in-stock sale, featuring a new curved front-lip design and stunning 'dirty champagne' anodization. It's since garnered enough interest to warrant an official re-release featuring several key design refinements. This R1 revision includes a newly-proportioned weight design, reworked corner transitions, an interior facelift, and a slew of new color options.

Designed to be differentiated

Derivative was designed to be a graceful balance between classic keyboard aesthetics and unique visual cues. Novel elements come together to create a distinct identity. A fresh & multi-faceted side profile, a subtle yet always-visible convex front-lip, and an inset two-piece weight with contrasting finishes are core concepts to the exterior design.

Function, and form

While not unlimited, Derivative provides excellent versatility by offering three mounting methods with distinct tactile and acoustic properties: o-ring gasket mount, top mount, and relief mount. In addition, several options for o-ring hardness allow for an even finer level of tuning towards your preferred typing feel and sound.
