The Forum seems to be broken at the moment so difficult to send replies....Toby, my problem is not to do with using A/D Input. This is about using the USB to play backing tracks. Whilst I do seem able to create a Live Set link to the individual backing  tracks, I'm yet to find a sucessful way to save individual audio volumes for each track. Wonder if you (or anyone else) have any ideas? I though the reply I found on a previous forum post was going to solve it but i can't currently make that work for me.
