I'm giving this 5 stars mainly because 1) the freeze function is incredible 2) most other free reverbs are junk (the exception being OrilRiver) 3) the CPU load is excellent.
I still need to see if I will use this very much for routine mixing tasks, but after spending just 30 minutes with it I know for sure I'll be using this for sound design, namely making organic pads. If you use the freeze function, or even just dial the decay time up to 100, this thing will make gorgeous sounding pads out of almost anything. So far I've mainly just experimented with single sound sources (piano, tuned percussion, synths etc), but the next stage of experimentation will be to use some bussing and/or sends to create some multi-timbral pads. As someone else pointed out, this reverb does not modulate the wet signal, but honestly it sounds pretty lush anyway, and I plan to bounce these pads I make to audio and then use other FX plugs (EQ, chorus, phaser, trancegates etc) to give these pads some life and movement.
