Been watching this emulation being developed and have been quite impressed so far..
Real nice feature is that you can save and import all your normal dx7 banks by placing them in a zipped folder called      Dexed_cart.zip --- must be placed in same folder as Dexed.dll
 
Plenty of sites with the dx7 bank syx files available for free ... google!
