Good point.... I have an MFC as a back-up... I'll try it with the XL setting... Maybe I can look at the Sysex Data setting in the MFC somehow...Glennski said:I don't own an MFC but as far as I know they posted an updated firmware for it in which you have to select whether you're connected to a Axefx MkI/II or XL. My guess is that they have different sysex IDs and all that may have something to do with it?
