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

Has anyone here worked with this? I have a PX-7, and was hoping that it could generate poly AT for my gear that responds to it. The manual says that it can generate Poly AT but not respond to it. From what I can tell, you can only insert/edit Poly AT in edit event mode, and not from the keypads. Haven't looked into this all the way, but I was hoping the keypads would generate it. The midi spec says no for respond, and generate is left blank. Any opinions welcomed.
Just got a Fizmo and looking to control it with the PX-7.
