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

Oh sorry let me clarify:
I have an XL7 with the Mophat, and Techno Synth cards added (Leaves me one slot,
I was thinking of getting one of the orchestral cards).  I also have the Audity
2000 w/OS ver 2.01, and just traded out an Orbit 9090.

Orbit/Planet Phat: Beats mode, like an appregiator sort of, but set up
specifically for the drum mappings.  You could only have one play at a time but
there was a rudimentary sequencer.

XL-1/MP-1:  Super beats mode, where not only could each channel appregiate
specific beat patterns, but you could assign a different "beat" to every key?,
thereby playing a drum set live.  Also mapped specifically for the drum sounds.
I think, but am not sure it has the beat patterns from before.  I was also told
that if I had the Orbit and the Audity together it was the equivelant of an
XL-1.  I really don't know how much of the original sample set for the XL-1 came
off the Orbit, but I suspect it was a lot?  Isn't this the same sampleset used
in the XL-7?

Audity 2000:  Has drum mappings and appregiators, but the appregiators don't do
beat mode justice.  Doesn't apear that the mappings match the drumsets at all,
they seem just like general purpose appregiator patterns.

XL-7/MP-7:  Built in sequencers, appregiators.  Also no beat mode though you can
simulate it using the triggers in latch mode.  As far as I can tell they aren't
mapped out to match the kits and are all general purpose synth oriented.  The
Yahoo FAQ says:

 "Is the Superbeats mode from previous Emu sound modules incorporated into the
Command Stations?
At this time Superbeats is not incorporated into the Command Stations. Because
they have their own internal sequencers, it is not necessary to implement a
Superbeats mode. Similar results may be obtained by using the arpeggiators if
needed though."

So now my main questions are:
Does the addin chip for the audity 2000 duplicate the Orbit/planet phat?
Will I get beats mode by adding it or only the soundset?
Does the XL1/XL7 duplicate the soundset of the Orbit 9090 at all?
