I would also point out that since the RME cards are locked into a
periods/buffer =2 it would seem important to me to be sure that the
1010 also works at that rate. I am fairly sure  that you cannot run
the 1010 and the HDSP using different Jack parameters.

However, when you get through all of this is seems to me that you'd be
as well off, if not better off, to consider an external A/D and just
use the HDSP's ADAT in's as well. I'm sure giving up the 1010 after
such great results would be a tough desicion though
