Emax

Hi,
Since 4 month i have my Emax now - i saved all my Presets with 
Midisettings in Omnimode. The problem now is when ever i want to play 
any other gear that is on the same midichain, the emax plays it´s 
preset too. I know i can modify each preset and set it to "poly mode" 
but thats much work to do... My Emax Presets are all on channel 11. 

I am just wondering if there is a global setting for all presets to 
work in poly mode. 

I couldn´t find anything in the manual
