I was under the assumption that the USB connection wasnt working on the Mackie unit... I could be wrong, they may have fixed the SW for the SDR. Check the Mackie Forum, theyre a great help... (no kidding!)
At least you HAVE a USB connection for your recorder. I got the Mackie HDR a couple years back and lemme tell ya what a B***H it was to get the FTP server working for file transfers...... PAIN IN THE BUTT!!!
I guess it makes up for itself in the graphic editing....
Lemme know how you like the converters in the SDR
