My ATE presets are not working either. I´ve imported your "on" EQ preset succesfully but I still have the same proiblem. The sound only changes when I´m on the option where the EQ presets could be created/edited, but once the preset is saved there´s no way to activate the preset. I already did. I´m currently saving my music files to the computer to format the memory card and try again to do a factory reset. Are you able to change among your different EQ presets without problems? Could you tell me what are the steps you´re using to activate a PMEQ preset? Maybe I´m doing somenthing wrongly.
