It sounds counter-intuitive to describe a freeware like you did. But strangely I was watching one of the only good comparisons of the II and III on youtube, and had already thought of roughly that description. Maybe that could also be termed harmonic separation? Anyway, I barely spent any time with it. My strings are about a month and a half old. And they sounded damn good when I installed the FW 10.After a quick run with old strings (yeah it does not count I know) I've been playing a lot lately, my impression is that the strings feel closer to new strings actually. Not saying the strings are new now, but harmonics and the upper frequencies seems improved. Basically I feel I get more for less, as if the overall "resolution" is improved. I can't wait to try this with new strings!
IMHO there is no way to hear this kind of difference after video compression, so I wouldn't expect to. [I'm also a 96K person, in terms of nuanced digital reproduction, for what its worth. That's different from fixed 48K processing, which I'm happy with or I wouldn't want a modeller that uses it..] But the subtle improvement did seem real, particularly when playing multiple notes with some dirt or saturation, I think particularly with some of them 220 hz. or below (where muddiness was a touch more experienced before, now the fuzz is less uniform and more nuanced per string). And I dare say not realer, since its a different real. ...IMHO.
