[A6] progam vs mix mode sound

[The Deliverator]

Hi All,

Thanks for the help the other day.  I now have a mix setup so that I have 4 midi channels that accept program changes on midi channels 1-4. The programs do change accordingly on the Andromeda.

I'm noticing something weird though.  When I play a patch in program mode, say for example 'warm strings' , it sounds very different in program mode than it does in mix mode.  This is the only patch I am playing, and it seems to happen even if I am only playing one note, so I don't think this is a voice issue.  

Any ideas?

Thanks again for any assistance and tolerance of n00b questions :-)
