DDJ SZ2 - Load Prepare FILES Mode

Hey Guys,

i'm using the DDJ SZ2 and the actual Serato version.

I don't have a Library, so i use the FILES MODE and play the files directly from my external HardDrive. Don't ask ;-)

For 5 years it was very good on the DDJ SX... now with the SZ2 we have the problem that we couldn't map the Midi-Files that follow:

The Left Load Prepare
and
the Right Load Prepare
Button are doing the same thins.... but i want to Map them like:

Left Button = Deck 1
Richt Button = Deck 2



do you understand? sorry for my bad english ;-)
