Okay, so I'm playing along to a midi learning new Dream Theater stuff and I notice that I'm out of tune. So I click into my tuner and it turns out I'm perfectly in tune - yet I remain out of tune to the midi and all other midi files I try out. I checked against a regular CD and my guitar is definitely tuned correctly to E standard. Yet what my computers midi output which claims to be the same tuning, while in tune to itself between tracks, is definitely not playing back in correct tuning. Is there some weird way the overall frequency of my midi playback could have gotten bumped off of the correct Hz values? If anyone can help with this whacky issue it would be greatly appreciated.
