I am selling this item as I purchased it used about a year ago but hardly used it. I have checked the basic functions such as power on, input, and MIDI input/output, but the screen has burn-in and the LCD is difficult to see, so please purchase it on the assumption that it will need to be repaired. The item includes the main unit and the dedicated case only. An AC adapter is not included. Thank you. - Brand: Yamaha - Model: QY70 - Function: Sequencer
