Alesis V25 25-Key USB-Midi Keyboard Controller. Purchased second-hand to try and learn digital music production, and didn’t have the time or patience to learn all the components. But, this device registered to my Apple computer with ease, and was really fun to play with! Fully functional, and will be shipped with cord and packaged securely. Dimensions are 21 inches wide, by 7 inches long, by 2 inches tall. Offers always welcome. Please reach out with the any additional questions!
