Freeware - zynaptiq SUBSPACE VST Plugin

https://www.zynaptiq.com/subspace/

SUBSPACE is a super-lush sounding and totally streamlined reverb plugin. It is based on the allpass reverb module found in our acclaimed MORPH 2, WORMHOLE and ADAPTIVERB plugins, and features just two controls: a switch that selects one of four presets, and a dry-wet control. Adding (inter-)stellar reverb to your sound was never easier!
