Have you tried the DynaVerb algorithm? Turn the reverb’s DECAY below 0.1 S, and it changes to OMNPR MODE. Move MIX to 100%, and there’s extensive control over compression, limiting, ‘dynamic reversal’, expansion, and gating. ATTACK and RELEASE can shape the gate, milder expansion ratios, or even Slow Gear / ADSR-type FX.
Sculpt, Crushstation [EQ Compressor] do a decent job of auto-gain-style compression, with built-in noise gating. Not too configurable, though. DynaVerb-as-an-Omnipressor is an amazing effect, with or without the reverb component in the mix. I believe that the parameter ranges may be wider than the original.
