Matt,
Note: Byron beat me to it, but here's some additional info.
Once you get the USB working, you'll love it!
Here's where you can get the AW1600 manual:
http://www.dijonstock.com/index.php?page=the-docs-pageI don't think a special driver is needed to "see" the AW1600 drive from a PC via USB. The only driver supplied was a USB MIDI driver, if I remember. BTW that is also available on the above link as 1600USB.ZIP.
No, you cannot export WAV files to the CD drive with the 1600.
Start by connecting a USB cable between your PC and the 1600. Turn on the 1600. Press the UTILITY button until USB is highlighted on the left. The CONNECT screen button should be blinking. Now press the ENTER button.
When connected via USB, the 1600 should appear as 2 drives: AW1600-1 and AW1600-2. The Transport folder is only on one of the drives (don't remember which). Note: There is only one drive in the 1600, but it appears as 2 via USB.
Do you see either of these drives via USB when following the "connection steps" above?
