I have confirmed that the power is on, MIDI devices are connected, and sending and receiving data with a computer is working. However, due to its many functions, I have not checked any other operations. There are noticeable scratches and dirt on the main unit. Please note that it uses a Dock connector. A genuine power adapter is included. All accessories are shown in the photos. Since I have not confirmed all functions, this item is being sold as junk. Thank you.
