Kurzweil KM88 has the first 8 presets, non-editable factory ones. All of them have preprogrammed first two buttons for browsing the multis up or down, The second preset is missing programming for going down mutlis. That means if I jump from multi 1 to multi 2, there is no going back to multi 1, I have to browse to all of 128 presets to go back to 1 (after 128, going up will go to preset number one), it is obvious bug, and I don't know how to solve it. Please help.
