This is one of my favorite things boy does this thing work really well I hate to kind of sell it but you know what I don't use it as much and I need the money this is makai mpk249 one of the best small keyboard MIDI controller you can get on the market. I don't have the plug but it's only five volts very easy to find and it's missing one knob that's it cosmetically it's perfect you'll enjoy playing this thing mind you now you need a computer as well as speakers to hear this thing it is a controller not just a regular keyboard retails for about 449 used you can get them at around $300 but today I'm pricing this baby to move a whopping200 dollars be the Envy of all as people look at you and wonder how did you get such a fine piece of equipment
