Hi Brad! Thanks for the reply.
I was using the data editor at the beginning. Then after some problems with the pedal functions, like sustain for all stage settings, I read about the stage filters in the keyboard and turn off the filters. Then I tried to edit and save in the keyboard, but had this issue with the target changing.
About the saving procedures, in the editor I save clicking in the rom( I guess ) icon. When I'm editing in keyboard, right after I got everything right, both sound and settings, I click Write, then I Choose stage setting as target, then enter again and confirm.
