I use nothing but the XG voices. Since I'm mostly interested in organs I can't use the panel organs as they don't respond to velocity either from the keyboard or midi. On the 740 all the voices can be routed through the DSPs. I can get 5 DSPs working on the same voice - you can get some pretty weird sounds that way. Also I layer the voices. Using multipart sysex I can put nine voices on top of each other, eight parts and one right voice. I keep the other eight parts for the styles and turn off the receive midi for them. This way I can use the keyboard for all nine voices but still get the styles playing properly. You can do all of this with the 2000 and higher machines.
