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

I'm still trying to wrap my head around sound design on the XL-7.
Unless I've missed something, it seems that some of the wavetables (a
surprisingly high percentage, actually) are samples of chords, not just
single notes.  Is there a reference anywhere that tells which chords
they are?

If I have missed something and they are programmed into the presets I'm
still curious which chords they are.  Some of the names give a little
hint but I'm wondering if anyone can make it a little easier on us
curious folks.

Thanks,

Chris
