Actually i dont really need new features for the arranger keyboards of today as a very large percentage of them i would guess are very nearly unused before a next instrument is purchased judgeing from the movement of instruments on this board. But what i would really ove he manaufacturers do is provide say a 5 disk dvd set that shows the features of the instrument from a musicians point of view. This probably wont ever happen because actually learning all the functions on your instrument would prevent us from buying the next "new thing " that has 80% of the features that we had on the last "old thing " that we did not use then and probably wont use now !

For me , definately the only thing i would need from the manufacturer is s series of instructional DVD's.
