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

Hi, I will soon be a proud owner of PX-7 and am thinking of expanding it with Pop Collection ROM. Now, I've heard an mp3 sample of the Simplex pad preset on synthmania's PK-6 page which I really like. This preset is only available as a part of additional bank on PK-6. The P2500 doesn't have it (at least by looking the manual). How's that since the ROM is the same on both? Will I be able to access the additional bank of PK-6 on PX-7 with this ROM?

Thanks!
