This multiple card option in totalmix exists as well for the fireface and the HDSP, but that's only to switch between devices, without switching the GUI. It has nothing to do with whether the CoreAudio driver combines multiple cards together as one. So it's not really true that the driver turnes them into "one big core audio device" for totalmix , because this is not possible (physically). The totalmix dsp is located on the PCI or cardbus card and only responsible for all channels on one card! Sending and receiving all channels takes a lot of bandwidth and without an additional bus connector or a totally hogged PCI bus, there will never be direct communication between multiple cards except for sync, totalmix _GUI_ and maybe similar ram allocation :) This kind of device combining is more something the Motu PCI-424 can do, not the PCI or cardbus interface for multi-/digiface. But it has other problems, so I stay with RME or Linx depending on the task. > since it only has one card bus and with Digi/Multiface you can only put > one breakout per PCI card or card bus.

Otherwise both cards will be recognised and everything, but you wont be able to choose both simultaneously in Logic, the old problem again. That was also why I argued with Matthias two years ago, when the fireface came out and I sold my threepack of Motu 896s. I thought combining was something that belongs into the driver, but he said it would be the applications duty. Well now it's in the OS, so we were both kind of wrong or right, depends on you point of view :)) Greetings, Daniel -- Daniel Hojka University of Music and Dramatic Arts Institute 8 (Jazz) Moserhofgasse 39-41 A-8010 Graz
