Logic cannot currently use 3 FF800s simultaneously via CoreAudio drivers. BUT: you can run a Fireface standalone. So you set up units 2 and 3 to be just A/D/A converters, and connect them to unit 1 via its ADAT and SPDIF. You'll still only get 20 i/o total at 96kHz however, due to the bandwidth limitations of ADAT (4 channels per cable at 96k). Note 3 pairs of the outputs would be unbalanced phones outputs. This problem will presumably go away soonish, when OS X 10.4 arrives with its support for "aggregate" (multi-device) driver combinations. Currently, using Logic and RME, to get >20 channels at high sample rates you'd need to look into their MADI card and breakout box, with appropriate outboard converters.
