I have had a week with no sync problems but today they began.
I just wanted to tweak the level of an eq stomp. After syncing the preset is fixed. Transfer the setlist to the pod. All woring fine when I select presets from the Edit program. As soon as I close Edit random presets are missing from various banks.
I started Edit again, opened the saved presets, they work, put them back into the right spot in the setlist, they work fine. Close Edit and disconnect the Pod and random presets are gone. I've tried various things, from leaving Edit open and disconnecting the USB lead to vice versa. Tried restarting the HD500X and no change.
Obviously this is a big problem for me so any help would be great.
