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

I just bought a MP-7 and I love it. Can't belive this thing is so
underrated. Mine has a XL ROM and Protean ROM.

Anyway, after getting over the Wow!! factor, I discovered I also have
a Soniq card. This ROM has amazing samples in it. Lots of arpeggiators
too. I can't find anything about the card. 

Does anyone know from what module a Soniq ROM is from? Or is it a
custom card? Just curious.

Thanks
