We brought you a video elsewhere but here's more of what RME are saying about the new MADIface XT which they tell us is the world's first USB 3.0 audio interface.
"It not only has 3 MADI I/Os with 64 channels each, but also 2 mic/line inputs, 2 XLR line and one stereo phones output, plus one AES/EBU I/O - a total of 196 audio inputs and 198 audio outputs. Plus several MIDI ports via USB, MADI and DIN. To use all this in a portable device with the typical RME performance, the XT uses external PCI Express and USB 3.0 to guarantee hi-speed data transfer. It also features TotalMix FX, can be used completely stand-alone, remote controlled via MIDI and much more."
