OS X blah blah OS X blah blah… oh wait just kidding! =8<>
I don't think the 001 was ever a TDM box was it? It was just an interface with some extra hardware in it. Yeah, according to this SOS article it's just an LE system with no TDM. It can run RTAS, but those are host based. So being an LE host based interface it wouldn't enjoy any TDM/DAE support.
But that said it doesn't mean that StudioVision would outright not support the 001. If the 001 was setup to interface with a standard ASIO protocol then it could. But Digi may have come up with something different for the 001.
If someone with a 001 installed SV 4.51 we could find out. :P

Oh here's something interesting, and this totally makes sense. On DUC they state that people have the 001 work with SV, but no one has gotten 24 bits to function. So SV will give you limited support with the 001.
