Deanne, the Roland VP770 (and the VP550 before it) will do this and a WHOLE LOT MORE. A little expensive but if you knew what it can do, especially when paired with an arranger, you'd probably consider it a bargin. Definitely, one of the most fun keyboards out there. BTW, I have a like-new VP550 that I'd let someone have cheap (I upgraded to the VP770). You can actually just TALK the lyrics into this thing (while playing the midi note) and it will 'sing' the song for you. Check it out at the Roland site.
