Emu XL-7 & MP-7 User's Group

Could I use the XL-7's return to get an external signal out its digi 
out put? I might get an additional soundcard which has an Spdif more 
than I can handle... I was thinking I might be able to use the emu to 
convert an external analogue signal to be able to use the Spdif to 
get an extra stereo track of simultaneous when not using the Xl-7...

Would this work? 


thanks....
