Korg Poly800/EX800 Users

Hello again y'all...Quick Question:

I just tried putting my Poly-800 on a single port with 4 other synths using the typical: card out-->in-->through-in->through-in-->through... configuration. 

But it seemd like the Poly-800 would only receive in omni mode no matter what I set the receive channel to.  

Then I tried plugging one synth's out into the poly's in, same issue.  It sure seems like something isn't right with the Poly-800.  It works fine otherwise.

Was I just really tired last night, or, can anybody suggest what was happening?

Thanks,
-Tim
