Apparently the hardware is cabable of it. The vendor's tech spec sheet: http://www.m-audio.com/products/en_us/OmniStudioUSB-focus.html If you can find one of these, get it. They've discontinued them in favor of the equivilent firewire device (FreeBob isn't there yet is it?). There's some out there at full price but most of the resellers cut the price and they all walked out the door in a hurry. Mark
