Hi Peter,
I tend to use the favourites section to quickly set up keyboard parameters rather than song, sound and style settings. I use my keyboard in a number of different MIDI configurations and if playing out I use different footswitch configurations to home.
When playing out to a predetermined program I tend to make use of the full 108 panel memories so that I can arrange my songs into a minimum number of files which can be loaded at appropriate break points in the program.
Cheers
Len C.
