I've asked the same question in multiple forums with no good results. I've got an AW16g that I bought new when they first came out . No usb so probably an earlier version of the 1600. It's completely silent and great for portable recording , but a "pain" for any editing. I use mine as a mixing board , just for all the inputs . It's lined out to my interface . After working inside of a pc daw , I really couldn't see using it for any other reason . I believe the majority of the reply's I got was , only the "transport functions" would work as a controller .. These are "GREAT" machines that bridged a wide gap between the analog units and pc daws. Mine was 1,100. US. so I refuse to box it up or sell it for nothing. Good Luck . Later .... mark
