Parting with this peice as I have no room for it. Basically fresh out of the box, unfortunately I lost the box and instructions in a move but I will have an attached file with the instructions manual attached. As mentioned above you can plug & play any sounds from a laptop or pc. It already has 7 built in instrument functions in which you press the respective function button and one of the labeled keys underneath (see picture above). Great for anyone interested in playing!
