Elektron Musical Instruments

Hello guys.
I'm still thinking about upgrading my SPS1 to a UW. But what I want 
to know is this:
1) I have an EMU world sounds synth, which, has some excellent 
ethnic percussive sounds that I'd like to be able to play/trigger 
using patterns created in the SPS1
2)whilst also playing sounds created within the SPS1 at the same 
time in real time into my sequecer Pro Tools 5 le.
 Is this possible with my current setup, just the SPS1?
If so could someone tell how this is to be achieved? I cant even 
manage to sync my PT with the SPS1 so that pressing play on one 
plays everything in in the SPS1 and PT in sync.
Or is it a case of having to upgrade to the UW where I can load the 
sounds straight into the UW and mix and match in the homogeneous 
environment of the UW? in which case I will loose in track count.
I need proper answers to one as opposed to 
"yes! I think it can be done. I've got a friend's mate's uncle's 
brother who once might have had this set-up maybe" as it could be 
quite costly.

Thanx
