Three plugins are free: Valhalla Freq Echo handles frequency shifting and analog echo emulation, Space Modulator provides flanging and doubling, and Super Massive offers reverb and echo. The listed paid plugins—VintageVerb, Delay, FutureVerb, Room, Shimmer, Plate, and UberMod—cost 50.00 USD each as one-time purchases. Product pages offer demos for Room and VintageVerb. Supported formats include 64-bit VST, VST3, Audio Units, and AAX on Mac and Windows; Audio Units are listed for Mac only. One purchase covers the supported formats for the DAWs the customer personally uses.

Mac installers are signed and notarized, and Windows installers are signed.
