I don't know if it is needed by anyone else. I finally got my Mackie Control to update the firmware using a small program suggested by Mackie called MIDI-OX
www.midiox.com It worked perfectly and very fast. I hope this helps someone if they are trying t upgradr the firmware.
But after updating the firmware, I still have no control of AA 1.5. So does this controller not work with AA 1.5?
