Just wondering if there are any members using an Onyx (1220, 1620, 1640) with Cubase SX3. and if so, how do you like it?

I recently purchased a 1220 and I'll be using it with Cubase SX3 and would really love to hear any pointers, tricks, tips or whatever as far as using the Onyx with Cubase! Setting up buses in particular... Help me get started any way you can. Thanks!
