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

im using a laptop with windows 98 and a midiman 4x4 midi/usb 
interface to upload and download patterns into my mp-7. i cannot get 
the midi conf. to say anything except "none" on the input and some 
kind of roland synth thing that came on the laptop already. is it 
possible for this to work, or is the midiman just not gonna cut it? 
also, if and when i get it to work, is it possible and/or worth it to 
replace the user presets with the xl-7 presets, so i can have both, 
or are they basically the same? 

by the way, when the usb connection on the command station works, it 
will be a new os right?
