The default tempo is &1000, which corresponds to one beat per centisecond; doubling the value doubles the tempo (ie &2000 gives two beats per centisecond), while halving the value halves the tempo (ie &800 gives half a beat per centisecond). The parameter can be thought of as a hexadecimal fractional number, where the three least significant digits are the fractional part.
