This version v1.0.1 on MuseHub is broken. It might work briefly right after installation, but upon subsequent restarts, it's dead. However if you get version v1.0.2 directly from mntra.io, then that one works ok, you just need to log in to their service.

BOREALIS-LE is the free version of BOREALIS, our dynamic reverb plugin designed for the studio, stage, and beyond. Featuring one of BOREALIS’ inspiring algorithms, it transcends conventional reverb plugins by allowing you to create an interplay between your dry input and its wet output, using its envelope follower and unique modulation possibilities. BOREALIS-LE allows you to delve into this unique world of dynamic reverb for free! The included ‘Sanctuary’ algorithm is an imagined inner sanctum with controls for the size, frequency tilt, rate of spatial modulation, and damping. With the included deep modulation system, equalizer, and limiter, BOREALIS-LE allows you to take this algorithm into many dimensions.
