Ok, firstly, he's asking about EZDrummer, not Superior Drummer 2.0 (thanks for pointing that out too Chris)
Have your PT session running and EZDrummer loaded.
Open the EZD Mixer window.
Select multi-outs - its should say Track 1, Track 2, Track 3, etc as you go across the mixer for each instrument in the kit. There are generally 8 outs (Kik, SN T, SN B, HH, Toms, Cymbals, Room, Comp)
Ok - you can close the mixer screen as sklitrip mentioned and re-open to check the assignments (if you like).
Make sure you have 8 AUX tracks in PT (if you already havent done this)
In the channel OUTPUT on your instrument track, you will see the option to output to plug-in EZDrummer=> EZ1, EZ2, etc..
On the AUX tracks, name the different tracks as per the mixer in EZDrummer (makes it easier than just trying to tremember which each Aux track is!) - Kik, SN T, SN B, HH, Toms, Cymbals, Room, Comp
Now, assign each AUX channel input from the EZD plug-in.
i.e EZ1 - Kik, EZ2 - SN T, EZ3 - SN B, EZ4 - HH, EZ5 - Toms, EZ6 Cymbals, EZ7 - Room, EZ8 - Comp (or something similar to this).
Now, you should have each track assignment from EZDrummer into each AUX track.
Test each channel but clicking (or using your keyboard controller) to test each part of the kit and that they are assigned properly.
Add another Aux channel for parallel compression to taste and away you go..
Also, if you are registered with Toontracks, there is a multi-out template for EZDrummer in their user download section.. free
HTH - I'm doing this all away from my studio rig and going from memory - excuse any mistakes if I've made any!
