Korg Poly800/EX800 Users

Thank you Marco,

Yes, I will do the battery mod, but for now, the problem is worst than I tought.  My poly do 
not retains the patch even when the power is on.  Let say I program a patch, I write it in 
memory, and after that if  I change the patch number and I come back,  I loose 
everything???

battery holder + battery assembly because I gig regularly with that poly 800 and it seemed 
much more solid (I have also a 15$ mp3 player with all the patches saved in my keyboard 
bag :) )
