Alright heres where we may have problems with the midi playback for those of us here who's midi device is "microsoft GS wavetable SW synth" (the standard midi device if you didnt pay extra to get a better soundcard). All you have to do is change guitar 2 (synthdrum1) to the "synth drum" midi and change guitar 3 (synthdrum2) to the "Melodic Tom" midi. Now your midi playback should sound a lot better. I would of submitted this with those settings already set but my midi device isnt "microsoft GS wavetable SW synth".
Another thing, i didnt intend the percussion (guitars who's notation has "x"s) to be playable or even considered to be played unless your a percussionist. I just put them in to add to the powertab and give it a more full orchestra sound.
