Just to clearify if anyone wants to connect the audya to a computer.
Whilst I did appreciate the replies to my post I have found out from AJ that by turning 'ON' the 'USB MIDI' parameter will not transfer the Data from the Audya hard drive to a computer, it is only for MIDI IN/OUT.
So 'USB MIDI' must be turned 'OFF' to transfer data.
