ARRGH!! I accidentally kept pushing the little save as button instead of the open button while auditioning pro channel drum presets and overwrote them with who knows what. I was really liking a couple of them now they are ruined. What is the easiest way to restore them to factory? I hope I don't have to re-install that takes forever without the discs to just pick out presets. maybe someone could just send me the drum presets? they are pretty small.
