I think a possible reason for this in the quattro is to ensure that 
customers eventually have to upgrade to a next gen device. From what I 
remember the win drivers will only allow stereo i/o at 96Khz. Even 
though it has 4 channels or 2 stereo devices.

If there was a Midiman rep on this list they could rebute that ;P
