Was that FL Studio you used? The guitar sounded identical to FL Slayer.
And that plugin has always been hard as hell to use, and I know that. So I guess my judgement would be a little biased if that was the case.
It sounded okay, but if it is in a format other than MIDI, it should probably sound a little more smoothed and refined, rather than the computer spitting out pretty sounding notes. A live recording would make it much, much easier to listen to
