It's a good thing that you don't need the word clock input for two to work together. From my experience, the D1010 word clock sync feature doesn't work. I've used a Lynx L22 work clock source to the D1010, and the D1010 continuously drifts in and out of sync. Everything else in my setup can sync to the Lynx word clock just fine.
I sent my D1010 to M-Audio for repair, but when I got it back, it didn't work any better.

That's very curious, I can lock mine (all three 1010s) to wordclock just fine, I can even use a varispeed-capable wordclock to get varispeed in sonar?!??
What i have found is that on my home studio computer, I CAN sync the deltas using the multi card driver mode (EPoX 9nda3J mobo) whereas when I take them to stick in the edit machine at work, giving us a total of 4 delta 1010s, I HAVE to use an SPDIF cable to sync them together (EPoX 9nda3+ mobo)
weird huh?
