If you're using midi backing tracks and haven't loaded the music into your keyboard using the GM2 to NX format selection, you need to try it. The NX format will convert your midi instruments into comparable, better sounding Technics instruments; a midi acoustic grand piano into a Technics acoustic grand piano, a midi trumpet into a Technics trumpet, etc. It really works! Since I prefer to use midi backing tracks instead of styles (I have erased and converted 759 songs that were saved to my keyboard hard drive and reloaded them into NX format), I am really glad I stumbled upon this. This is a terrific capability that Technics has added to their instrument. My hat's off to them! I just wish they would have explained the NX sound capability better in their manual.
Happy midi-ing!
