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

Last night I was trying to get some live sets down, and I 
noticed my MP-7 clipping. Its definitely the EMU unit not my mixer or 
other instruments. Furthermore it was clipping only when two 
different tracks were unmuted i.e. it happens on single tracks but 
also seems to be a cumulative effect. I tried to turn down the 
resonance on those patches all the way, but that made my sound thin 
and weak. The resonance was not particularily high to begin with. The 
clipping is a definitely audible click and occured most noticeably 
when I had a Kick drum track in conjunction with a Bansuri flute 
patch. Has anyone else noticed this problem? I dont know the solution 
exactly, should I turn down resonance, track volume, or master 
volume, I obviously want to compromise sound quality (i.e. resonance 
timbre) as little as possible. I didnt even know that the MP-7 COULD 
clip, I know that mixers can clip, but didnt know that ROMplers can 
also.

Thanks,
