I can add now that the card does not work reliably in class compliant
mode with external sync clocks. It will randomly switch back and forth
output channels in banks of eight, cause clicks and distortion and
aliasing artifacts. Note that Motu will not provide you with tech
support unless you register your product and use a special tech support
system, they refuse to provide tech support via email. I am trying to
avoid them as manufacturer in the future wherever I can.

best, Peter
