Im trying to learn thing with guitar pro. Everything I hear regardless of the tuning is like flat or really out of tune with my guitar. My guitar is in Standard but doesn't cope with the sounds coming from the pc. I don't know what to do!!! Its really bugging me because its hard to learn songs when the sound isn't fixated to whatever tuning I want.
You can change the tuning on the instrument (if the tab is tuned flat) to standard by double clicking on the guitar tone (for example, Overdriven Guitar). If that doesn't work, check your guitar's tuning.
The problem could be with your strings intonation
try checking your 12th fret harmonic against your open string with an electronic tuner
