I hope this is the place to post this but...

I broke my index and middle finger on my left hand a few weeks ago so I've been unable to shred, which only left me to write some music on Guitar Pro so I have new material once I get better. But the problem is that I'd like to find a program that plays the notes in a realistic fashion, like a better version of the RSE on GP5. Something that isn't so fuzzy and inaudible, considering the combination of fast solos I have been writing, and the slow, kind of clumsy procession of RSE, it doesn't play or sound good. Does anyone know a program that can do this, make MIDI sounds become realistic (better than RSE)?
