I mainly used it connected to a PC. The pads are generally in good condition. The main unit has been initialized. The screen protector has never been removed. I lost the original AC adapter, so a separate AC adapter from another manufacturer is included. A bracket that allows you to adjust the angle has been added to the back. It's attached with double-sided tape, so it can be removed. Product Description The MPC One, a standalone music production center, combines intuitive operation with powerful features. The AKAI MPC One is a standalone music production center that works without a PC. It features 16 RGB pads, a 7-inch touchscreen, and a wealth of synths and effects, making it a compact beat-making machine that can handle sampling, sequencing, mixing, and instrument playback all in one. - Model Name: MPC One - Brand: AKAI - Accessories: Power adapter, manual - Firmware: 34.2 - Control Surface: V0.10 Thank you for viewing. #akaimpc
