Yes Donny, the MPP is a great tool for those songs that you just can't remember because they are requested so infrequently, or for those songs that you feel like playing sometimes but couldn't be bothered learning.It is a bit pricey but a one off purchase, with years of use.
And to Bebop, if I remember correctly the E50 and E60 can also read notation/lyrics/chords.Its a pity other makers couldn't adopt a few of Rolands' very handy features.
