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

I have some questions about the new OS... won't be able to try it 
before the emu guys have repaired the XL-7.

When I selected a new pattern (OS 1.01), Program Changes, Volume 
(CC7) and Pan (CC10) was automaticly sent to my external synth, which 
totally messed up the multisetups of the synthesizers... 

The multisetups of the external gear already has information about 
pan, volume and instrument, so I can see no reason why the XL-7 must 
send this info.

Can such messages be blocked in the new OS, or will I have to buy a 
MIDI filter just to do this simple thing?
