If i'm understanding you all correctly, I can connect the Ensemble to the FireWire 800 port on the Mac and i can connect the FireWire Glyph as a daisy chain to the Ensemble?? just a gut feeling, but it seems to me like this could create problems.
Yes. It sounds like you're scared by the fact that data for both devices ends up on the cable between the computer and the first device. But as mh explained most computers only have one FW controller anyway, meaning that if there were multiple ports on the computer they eventually combine to one data stream. In other words, the "Y split" is either going to be inside the computer or inside whichever external device is first, and there's no reason one should be better than the other.
