This is the way arranger voice sets should be... The CLP170's specifications show that 36/54 mb's are dedicated to only 38 sounds and an additional 10mb's dedicated to the XG voice set... Imagine having an arranger with the basic 38 instrument sounds from acoutic painos, wood winds, reeds, and so forth, and having 36/54 mb's to just those sounds... Having 10 mb's just to the XG voices would be great too. It would be great to have a arranger like this but also left some memory to add your own voices too Anyone play this piano yet? I would love to hear the 38 sounds on this thing...
