i don't understand why when you save a performance your rotary knobs that help you tweek sound (drastically) do not get disabled... sure you can call up a performance but you have to remember where all your knobs were set? might take a minute to figure out the sound you had for that performance like that. am i missing something? just seems like when you save a performance and call it up again the rotary knobs should not work, see what i'm saying? they should be taken out of the equasion..... sorry, newbie.....
