Dennis and Ulrich,
Thanks very much for your feed-back. It certainly sounds like a great product. When I wrote my initial post I am sorry that I did not express myself very clearly.

What I meant to say was that if I am using the keyboard (interface) and looking to upload a file from the hard disk, normally if I have a SCSI hd connected as well I can see the FD, HD and SCSI disks. I can then select which disk I want. If the USB is working and my computer is on, then looking from the Keyboard interface do I see the computer's HD as well as the FD, HD and SCSI disks?

The USB's manual that I read seemed to be a little vague on this. It gave me the impression that looking from the Keyboard interface, I would only see either the HD or the USB's attached Computers's HD, not both together. SO if this was so, what would be the switching mechanism between the two?

In consideration of your comments, this question may only be accademic, because no one would normally operate (during live performance) in this fashion.

Having "talked" it through with you, I don't believe it is a critical issue for me now anyway. But I would still welcome your comments.

Regards,

Jon.
