       Starts playing the specified MIDI file, first stopping whatever music was previously playing. If the loop

       Returns non-zero if an error occurs (this may happen if a patch-caching wavetable  driver  is  unable  to
       load  the  required  samples,  or at least it might in the future when somebody writes some patch-caching
       wavetable drivers :-)
