apVerb is an audio plugin to create algorithmic reverbs with exceptional smoothness and flexibility. The plugin generates reverb from thousands of semi-randomly spaced delay lines - inspired by a recently invented form of noise called 'velvet noise'.

The carefully spaced delays offer resonance-free reverb tails that can surpass the smoothness, flexibility and stereo width of traditional reverb algorithms. The delay lines are processed by filters and effects to achieve all kinds of reverbs and innovative effects.

apVerb provides full control of many parameters over time, thanks to the 23 curve-based multi-segment envelopes. Besides traditional reverb types, this enables the creation of reverse reverbs, reverb losing density over time, increasing frequency bandwidth over time, delay-like effects, ...

Additionally, apVerb can sync all envelope and pre-delay times to the host tempo, making it possible to create rhythmic effects. It also includes an early reflections generator based on simulated virtual room geometries and 3 effects: chorus, phase distortion, and saturation that can be applied to user-defined time/frequency regions of the reverb.

This is phenomenal, one of the best algo reverbs I've seen. It's not trying to emulate anything, but it covers all bases with a beautiful sound, from clean and natural to pretty out there. The main bulk of the controls as you see is bezier curves, allowing one to shape the reverb all sorts of ways. Quite fun. And if you like it, do try the other apulSoft products, you probably won't be disappointed.
