I write my riffs in FL studio in midi, export, then import into both GP and PT in guitar standrard tuning, and I get different reults in both. Not only that, but the second time the riff plays, it gives me different notes, yet, they sound exactly the same as the first tme it played. MAKES NO SENSE.

46564631, first time
41114131, second time

Mind you they both sound exactly the same in GP. How is that even possible? What is happening.
