This is an EDIROL MIDI KEYBOARD CONTROLLER PC-50. I bought it used from SOFMAP (inspected by SOFMAP) a long time ago, just the unit itself, and left it untouched. I have confirmed it powers on for this listing. (USB-TYPE B. The cable used for the power-on confirmation is also included.) I bought it before my child was born, intending to use it when they got older. I'm listing it now to make space for my child's belongings. Please feel free to use it. I have confirmed that it powers on, but please understand that I have not actually used it. Please assess the condition based on the images.
