This Yamaha PSR 240 keyboard features 61 touch sensitive keys and portable grand piano tone setting. It also features Yamahas exclusive Yamaha Education Suite which will actually each you to play piano. It has a hundred preset rhythm patterns complete with intro/outro, and fills A and B. It features a hundred synth voices from piano to strings and horns to drums. This keyboard has stereo speakers, headphone output, midi in and out, a sustain pedal jack, and will operate on a 110 dc in (adapter included), or six "D" cell batteries. As mentioned, this keyboard comes with a power supply adapter and a fully adjustable stand. The stand has been dented on one foot (see picture) but this doesn't effect the performance of it at all. This unit is ready to play right out of the box. I'm getting ready to travel so I don't have room for all the "extras" anymore and this one's gotta' go! Please feel free to check out my other auctions.    Good luck
