Spin to master. Unlimited control.
KnobKey is a precision metal rotary encoder that brings tactile, deliberate control back to your desktop. Featuring CNC-machined aluminum with a satisfying damping feel inspired by high-end camera lenses, KnobKey makes every adjustment feel intentional.
What makes KnobKey the ultimate precision tool for your UltraBARX.
CNC-machined aluminum alloy with a knurled dial delivers a "Vault-Dial" tactile experience — smooth, silky, with a satisfying auditory click at every increment. Each turn feels like handling a precision instrument.
Responsible for stepless precision tuning of volume, color temperature, brush size, and more. No stepped increments — just smooth, continuous control that responds to your every movement.
Assign any action to KnobKey's rotation — volume, screen brightness, AC temperature, brush size, timeline scrubbing, zoom, scrolling, and more. Configurable per application or scene.
Links via the QuantumLink™ magnetic protocol, seamlessly integrating with CoreBar and the wider UltraBARX ecosystem. No cables, no pairing — just snap and start spinning.
KnobKey integrates with SceneShift™ AI, automatically changing its function based on the active application or workflow. In Photoshop it controls brush size; in Premiere it scrubs the timeline.
KnobKey modules can be stacked together via QuantumLink™. Start with one, add more as your workflow grows — each module adds another precision dial to your arsenal.
