Tom,
I agree with you. All that wasted wave ROM on sounds I will never use, but not everyone would agree with you. It all depends on what MY favorites are. Some people. like Pilot, use the XG voices extensibly, because they can be tweaked, to his liking. Bluezplayer would use the synth sounds. I would probably never use the harmonica, accordian and musette, but would like more organ voices. UD would use the electric pianos, etc. Ultimately it would be great if we could customize the keyboard to include the voices WE want.
