This is a Roland MC-50 hardware sequencer. I purchased it new in the 1990s and used it, but it stopped working in 2025, so I am selling it. It is being sold as junk. It powers on, but nothing is displayed on the LCD, and it does not function. There is no unusual feel to the buttons or dials. Although I haven't checked everything, it used to work. I powered it on to take the photos, but the AC adapter is not included. There are no other accessories. Only what is shown in the photos is included. As you can see in the photos, there are signs of use and scratches. One of the rubber feet is missing. There are also signs that I tried to repair it, as the back cover has been opened. Please understand this before purchasing. - Brand: Roland - Model Name: MC-50 - Type: Micro Composer - AC adapter and other accessories are missing. Thank you for looking.
