Please note that this is NOT the stand-alone MS-20 synthesizer, but the controller that goes with the Korg Legacy Series virtual synths. It works great with the virtual MS-20. By remapping the controls, you can also use it with other virtual synths by Arturia, Cherry Audio, etc.
This controller is in very good shape. There's a small chip in the end piece corner by the serial number plate, but that's about it (see photo 7). It will be shipped with a USB cable and 3 patch cords.
