Yes, Alesis should be clearer and more specific when listing the updates, and also include all the info needed to choose correctly. Thank you for the reply. Just to be clear, all my boot, sys, and snd files seem to be up to date, the only update I should need would be to install the 1.01b(Pro x hat) triggers in place of the 1.00a(real hat) triggers. Is this correct or is it necessary to place all of the files?
