MIDI has no analog audio sound at all in it. It is just machine control data, sent from the computer to your JV-50. You apparently have hooked up the MIDI cables for the data side, but have not hooked up any Audio Cables for the analog sound output.

You also have to hook up Audio L and R outputs of the JV-50 to the Line Inputs of your soundcard using proper shielded audio cables and adaptors if needed in order to record that data to Audio tracks.
