hi and thx for your lengthy description!
actually, i just got yesterday my 14MXR and had no time to check it out yet - since i'll do some workshop for ADJ europe at their dealer day and open day events in kerkrade, i definitely have to do this very soon
i will use your feedback for testing and will post back here. if you need answer sooner, you probably might want to write to ADJ support, though. i cannot answer your question right away atm.
