A friend of mine has asked me this question. Please assist me if i missed anything out. On the cons i told him that he would be giving up aftertouch,upper 3,better screen,hard drive. On the pros i told him the s950 has more megavoices,s art voices,cool sweet,live than the tyros 2 as well as VH2, expansion slot for styles,sounds, audio styles,more indian sounds and drum kits. Did i miss anything??
