From: Krzysztof Helt krzysztof.h1@wp.pl
The wss_base is disguised parameter for one function. It is converted to a function parameter.
The code_type is only set but never read. It is removed.
The midi_vol is set only to 0 so it does not work as detection of change in midi volume. It is fixed.
The xport variable is alias to the port[dev]. Use the port[dev] directly to increase readability.
