Geez... 580kb and 260kb... That's not good at all.... If it were 1mb then that would translate into 1000kbs... Why didn't they just add 1 mb to both boards???? If the PSR-1000 is only 260kbs, then that's not much space at all especially since everything is stored there including voices, styles, songs, ect.... It's fortunate my PSR-550 has separate memory for styles.. I think it has over 7,000 notes for style recording and you can get like 135,000 notes for song recording.. How hard would it have been for Yamaha to add 1mb to the new PSR's??? I doubt it would have cost much..
