Yes, that is the problem. When I saved them(full extended save,except all custom). I had expected composer would be saved along with panel reg. When I originally saved them to SD with extended save, they load with no problem. Now , I load the file from SD, and press the "set" button to put it in Bank 1,slot 1 eg. The new composer A will not come up.
