Digital pianos with card reader

 

— the card reader allows the tool to work with removable memory cards. The possibilities of using such cards may include copying music recorded by a sequencer (see the relevant paragraph), playing backing tracks that play the role of accompaniment, loading new timbres or auto-accompaniment styles, and more; the exact set depends on the Digital Piano model. Note that the card reader is especially convenient when exchanging data via a memory card with a laptop: most modern laptops are equipped with their own slots for memory cards, and you can transfer data without occupying USB ports (often it is even faster).
