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

Hi all. I cant get Prodatum to edit patches parameters on currently selected patch on my XL7. Midi activity leds blink whenever a virtual knob/button is tweaked but theres no realtime change in the sound. 
If I save the patch on the CS (using Prodatum's save option), the modified patch get saved on the CS as it should (only then I can hear the results of the edition).
Should I change something in the Midi options of the XL7 to receive or update changes? Maybe something in Prodatum?
