Guitar Rising???

I heard about this a while ago, can't remember where (maybe recording magazine not sure). I initially thought it was a mod so you could use your real guitar as a controller. But this idea is quit a bit better. I'm not sure if it's something I am gonna be willing to shell for but yeah it seems to be aight. The only downside that I can think of is if the song list sucks or something.
 
The makers of Guitar Pro should implement an accuracy meter into their program. Problem solved! (and you can have access to more than 30 songs) ;)
