Macro-First Interface

Hearth is deliberately macro-first. The Hearth knob is the primary control: it moves the device into a warm operating region quickly, then the surrounding controls handle source-specific refinement.

That structure keeps the first move musical instead of technical. A user can decide how present the effect should be, then adjust brightness, density, stereo safety, or level only when the material calls for it.

• The main macro reduces auditioning friction by making the effect more or less present with one gesture.
• The underlying lanes and Warmth Servo stay available, but they do not become the starting point.
• The same workflow works across vocals, guitars, synths, and buses before finer source-specific adjustments.
