Where are you talking "slots" John? In the audio settings where you set outputs? The MOTUs show up as PCI2048 1-2, 3-4, 5-6, 7-8. When I add the second it says PCI2048(1) and PCI2048(2) and then the 1-2, etc.... so if that is what you mean by slots, it never gets beyond 8 entries.

What has me pulling hair is that it sees both, accepts both as valid (deduced by the fact that it accepts the setup of both), andthen dies when I hit play. Just so strange. I would think that if Real Band had an issue with me using both that it wouldn't allow me to set them up. It would fail when I set the output ports with some kinds of "not so fast, buddy..." message.

Really a puzzler.
