Hi there. I need to change the midi channels on the "midi" page on the menu of the keyboard. Anyway, also if the manual says that when i change something on the menu, it will remain saved when i go out of the screen, every time I swich off the key, on the follow swich on I need to set the midi channels again. Does anybody know how to fix and save my personal setup for the midi channels to avoid to reset it every time I switch on the key? Thanks.
