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

hi, I've spent my night trying to upload to my xl7 the preset
extension from rob papen for the techno yard rom.
I've chosen the file for rom without demo song (I don't find any demo
on mine), I've loaded the midi file into cubase and play throught the
midi out of my evolution controller (don't have any other midi interface)
midi in was flashing on the xl7. at end I've found all the preset in
the correct user bank, but lots of them sound the same, a sort of pad
with an LFO on the pitch! I've checked how they are programmed and the
"bad" sounds have layers with xl7 rom instruments, or they don't have
instruments at all...
other preset are better, but I cannot assure they are how they should
be...
then I've tried with midi-ox with different transfer speed and buffer
size but no luck.
then I've tried to upload the bank from emu site "xl1 patch for xl7"
and I have the same kind of problem.
what I'm doing wrong?
maybe is the midi out of my evolution keyboard? for everyday
sequencing work it has always been ok.
some suggestion please! don't want to pass another night in the same
way...
