I just replaced my tascam DM-24 with a focusrite octopre. Unfortuantely I can't get rid of digital distortion despite that the octopre says it's locked. I've tried using the octopre as the master, the motu as the master both via wordclock/bnc and adat. I've upgraded and installed the latest PCI-24 card software for Windows 7 64 bit to no avail. The adat bank on the motu just shows up with orange LED's on the inputs and the cumix shows each channel as being pegged out.
