I am selling this keyboard because the number of keys is insufficient for my needs, and I am looking to replace it. ※This listing is for the keyboard itself only. KORG microKEY2 Air Simple yet capable of rich musical expression. The 37/49/61 key models are equipped with an assignable switch jack on the side of the unit for connecting a damper pedal (sustain pedal). They also feature separate pitch bend and modulation wheels for real-time sound manipulation.
