User Comments & Reviews
Blue Cat Audio's free plugins have had a staple presence in my arsenal since the first time I came across them. Free or not, these plugins maintain a distinct flavour that makes them my absolute go-to plugins when the situation calls for it.
This group of plugins has the added bonus of full automation and MIDI interfacing, and a standardized configuration template that easily melds them into any DAW configuration. They couldn't be easier to use at any experience level, allow very fine incremental adjustments, and are thoroughly optimized for resource consumption.
