Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking.

If you have the old 5-pin MIDI ports on the piano, you can connect directly to a sound module (basically a synth without a keyboard) that also has these ports.
But if you only have a 'MIDI over USB' port, a host device will be needed. This generally means a computer.
