Rob Helms, you are right about RealTracks, many times it generates out-of-tune notes in the chord, aka sour notes. There's nothing you can do with sour notes except for having to regen.

Regarding to guitar solos, I can play very well but I'm still not Slash, so when it comes to emotional shred part with continuous 32rd notes, it's game over for me. That's why I need to rely on virtual guitar to generate Guns & Roses level solos to be put in my production.
