I purchased this several years ago and used it a couple of times before storing it. The only included accessory is the USB cable shown in the image. The Transfer ID is not included. I will also include the book I bought with it at the time. Thank you. A MIDI controller with 16 pressure-sensitive pads, allowing for intuitive operation. - Model: MASCHINE - Color: Black - Number of Pads: 16 - Control Knobs: 1 - Number of Buttons: Many - Connection Method: USB Thank you for looking.
