Nick, you need to ask me first if I HAVEN'T played one before you jump to that conclusion (mind you, you are not alone!)...

Yes, I've played a PA1Xpro, heard it there occasionally, and users of PA2Xpro's have remarked than nothing has changed. Good enough for you? (probably not )

But, rather than pile on MY back, why not interrogate those owners like leeboy who actually OWN one and report the problem, or AJ, who used one to make the examples? Perhaps it would just be harder to play the same game with someone that owns one?

Look, we all miss a lot of things while we are playing. Sometimes just concentrating hard enough to get the chords and melody correct takes a large part of our thoughts. Why not record yourself play, and see if you can hear the glitches afterwards..? To be honest, trying to dismiss AJ's examples as a corrupt OS strikes me as desperation, or at least fishing furiously for ANYTHING to deny the proven...

Please, guys, why not stick to beating up on fellow owners that hear the problem as well as I can... At least you have less assumptions to get wrong...
