A portable keyboard with a built-in card reader capable of loading performance data recorded on Play Cards, which feature sheet music on the top and a magnetic strip on the bottom.
In a unique design twist, when the player slides a Play Card into the reader, they can easily read the sheet music on the top while the reader interprets the data.
