Hi.
As I see it, the Data protection is there to protect your own work that you do on the keyboard and to follow this up the expand filters are set also to save your own work.
If you are using and inputting other peoples files then the appropriate filters need to be off if you wish to not change your own set ups e.g. on E.Q and Tempo etc.
And now probably thats more confusing than ever.

Regards
Peter
