Everything works as it should. This is a very light keyboard with Motiff-derived sounds. It only weights about 10 lbs. It features a large selection of high-quality Yamaha sounds, including grand pianos, electric pianos, organs, strings, guitars, basses, brass, synths, drums, and more. It also includes built-in rhythms, performance controls, pitch-bend and modulation wheels, USB/MIDI connectivity, and options for layering and splitting sounds. Great keyboard for live performances, church, band rehearsals, home recording, or practicing. All keys, buttons, display, and outputs are working properly. Includes the power supply. Its missing one knob see picture but it still can be turned. Normal cosmetic wear from use, but it works well and sounds great.
