personally, i find prodikeys lousy. i've got one maybe 2 years back, in less than a year the keys cant be played haha... all spoilt liao. i wouldn't reccomend prodikeys, the program is .. nothing special too. Are you looking for a sequencer with piano roll? or do u need auto-accompliment , band in a box is like auto generated chords n stuff. I think most sequencers will have the piano roll function, so u can drag the length of the note etc etc, no need to read sheet music.
