You can use the Universal Keyboard as stand alone music instrument with a touchscreen tablet or you can connect it (via USB) to a real world music keyboard and use it as sound expander and midi recorder. You can use more than 1000 build in sounds and you can create an endless number of new sounds with the 9 synthesizer engines and 20 sound effects. You can also import 3000 wave samples and Sound Fonts and modify them with the effect chains to create any sound you want.
