I find IK Multimedia to be inconsistent as to whether I like their plugins or not (my opinion, you can make your own). This one really hits it and has some interesting analog vibe going on. The channels even have some crossover and interesting phasing (of a good nature).
I’m not sure what the left/right differences are about in the harmonic analysis. IK Multimedia always seems to test out with some unusual anomaly, perhaps this makes them more “non-linear”? Their UIs always seem a little sluggish to me, but maybe that is a “non-linear” thing too. OK, this is not a review — you decide.
