Made by PreSonus, this is a DAW control surface/physical controller. I haven't used it much, so I've only used it to confirm its operation. The previous owner purchased it new from a retailer and didn't use it much, so it's in clean and working condition. It comes with the original box, manual, and genuine power cable. Only the USB cable is not the original. Regarding serial registration, the previous owner has already deregistered it, but I was unable to register it myself, so it's highly likely that registration is not possible. However, I was able to use and update the firmware without serial registration (Windows 10 environment).
