Hi Sunny,
Once you load the Wave file into the Expansion memory, did you create a custom voice? Once you create a custom voice, I'm pretty sure you can add effects in that section of the voice creator. I forget which page of the User Guide that is in, but you may want to check that section of the voice creator once more and look at the effects section.
Once you add the effects, then you can save the voice and then link that voice to a Registration and use that registration to recall your Organ Sample.
I'm not at the keyboard right now, but I'll double check my facts and respond.
Good luck
