Korg Poly800/EX800 Users

I just came across a yamaha sy55 synth sample cd can the .syx files be 
used by my korg poly-800?  Sorry I just bought one of these as my first 
anologue synth, i'm very new to whole synth/midi/patches/sequence world 
and know very little..

It has the moog slayer mod already on it and im thinking of changing 
the pots, but i stupidly took out the battery's and lost all the 
patches, so i've been slowly patching them in myself but have little 
experience with this kind of thing and is a slow proccess. What the 
best way i can get a new set of patches?

sorry, i dont want to bother anyone with my own troubles, but you know 
how hard it is for a noob
