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

Hello,
I'm new to the group here and I think it's great. I just recently
picked up a used MP-7, to replace my good ole Alesis MMT-8.  I quickly
loaded the MP-7 up with my World Exp, Beat Garden and Pop ROMs and
have been having a blast with it.  Killer box. I'm familiar with the
P2K synth architecture, just trying to learn the sequencer part of
it.   

I have a couple of newbie questions.  I cant seem to get the MP-7 to
respond to the mod wheel on my Evolution MIDI keyboard.  Patches in
which the mod wheel worked fine when the ROMs were in my Proteus 2000
do not respond to mod wheel at all in the MP-7.  The other controller
knobs on the Evolution work fine though.  I've tried everything I can
think of to get it to work. Any ideas? 

The other thing I haven't been able to figure out is how to delete a
song (other than reinitializing the whole box). The manual is
strangely silent on this (or I overlooked it). 

Any help appreciated!
