For music and song producers, this is an FL Key 37 piano specifically for the FL Studio application on computers. I bought it a while ago and no longer need it. I only used it a few times. It's new, but it's missing its cable; I lost it. It's available on Amazon for cheap. I bought the device for 900 new, and we won't disagree on the price, God willing, because I don't need it. I accept a slim acoustic guitar in exchange.
