Digi 002 w/external effects processor ?

[moonmusic]

O.K...I'm excitedly awaiting my 002 and am wondering how I'm going to patch my Ensoniq DP4 through the 002....Here's the configuration...
channel 1 - Neuman U87
channel 1,2 - EMU PK-6
channel 3,4 - EMU PK-6 SUB
channel 5,6 - Ddrum 4
channel 7,8 - Ddrum 4 SUB
SPDIF IN - Gigastudio 96
I'm guessing I can just push the button to change between channel 1 XLR and channel 1,2 to toggle between the U87 or the EMU when recording...I want to use the DP4 like you would in an aux send/return configuration so I can add the effect to whichever channels I want during recording...I don't think this thing has aux send returns does it and is this possible? If so how?...Thanks for any help....Ted
