Madrona Labs released Aaltoverb, a reverberator designed with a focus on completely smooth tweakability. Any of its controls including the reverb size can be adjusted without making clicks. This feature can bring fresh sounds to a mix, and particularly shines in a live performance setup.
Aaltoverb is directly available at the Madrona Labs website for $35.00 USD.
