No guess on the origins of the name ‘K’
Can you expand on what sort of algorithm you’re using on the compressor?
Without specifically criticizing any VCVRack compressor, I have to say that I’ve not been impressed by the usability of any of the compressors available. When I’m on my Windows box, I end up using Audiodamage RoughRider2 a lot, which isn’t a super-duper pro-grade compressor either, but it sounds better/more transparent than any of the ones available for Rack.
