I have owned this keyboard from new. Only selling because I have a new keyboard. I actually bought two of these originally because they are so useful/reliable and will fit in a large suitcase. This is the second one I am selling. In perfect working order-uses usb power -plug and play into most devices. I have used it mainly with garage band via usb cable. Unusually it has an expression pedal input which works with the Roland EV5 or EV7 pedal, which is very useful feature and the reason I bought it. Also the light up octave keys are a nice touch.
