— Why free

one engine.
two editions.

The free 1snob edition uses the same DSP engine as the paid Full edition. The difference is the wrapper: 1snob exposes one knob and one fader; Full exposes nine knobs, A/B compare, a preset browser, and Freeze. The reverb itself is identical.

The free build is unrestricted. You can ship records made with it. You can install on every machine you own. There is no email check, no online activation, no nag screen.

Honest disclosure: the download link is currently sent by email while the public 1.0 is staged. The build itself is the unlocked free edition.

— What you get

one knob, the whole room.

The 1snob knob takes the engine from a tight, dry corner (k = 0.0) through a natural room, into a musical bloom, then into the plugin's own voice, and finally into an infinite ember at k = 1.0.
