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

Last night I did your trick of clearing the patterns on my ER and 
EA, so now not only does the sequencing work, its also so cool that 
I can switch the groovboxes off/on with the track buttons.
Do you know an easier or more elegant way of putting patch changes 
in, rather than manually editing on the XL, which I think is a pain 
in the ass?
Anyway, mucho thanks, the setup is way, way addictive now!
