Some features of keyboards include chord recognition, demonstration songs, touch sensitivity, after touch, polyphony, multi-timbre, split point, accompanying tracks, tempo, auto harmonizing, pitch bending, vibrato, drawbars, and piano action to mimic the feel of a traditional acoustic piano while playing.
