Before evaluating the software, it is worth understanding the use case. You might need the V.I Suite if:

: For VST hosts that only support 2-in/2-out plugins (like some older editors), the suite includes three pairs: : Front Left and Front Right. : Center and Low Frequency Effects (Subwoofer). : Surround Left and Surround Right (Rear). Key Features & Controls Width Correction

Users can adjust the amount of extracted ambience sent to the front or rear speakers independently.
