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

Hello everybody!
I like to sketch out my tracks on the XL-7 and then sequence my sampler (Emu Esynth) with the XL-7. I got my samples organized in 128s, one sample on each note. So I'm wondering if there's an easy way to browse thru my samples by changing the midi notes of a track (especially individual drum tracks).

Any feedback will be highly appreciated! :-)
