Read up on VST instruments. You need them to hear sounds. Cubase comes with a few, you can get a whole bunch of freeware ones at KVR : Virtual Instruments, Virtual Effects, VST Plugins, Audio Units (AU), DirectX (DX), Universal Binary Compatibility - Audio Plugin News, Reviews and Community

The Oxygen8 does not have its own sounds. It's known as a controller keyboard or MIDI controller.
