Miles 2 uses the default MT-32 pitch bend range of 12 semitones for its AdLib
driver. Miles 3 switched to the default GM pitch bend range of 2 semitones for
AdLib. ScummVM would always use the Miles 2 pitch bend range, which caused
pitch bend for Miles 3 games to sound wrong on AdLib.
To fix this, a property was added to the Miles AdLib driver to specify which
Miles version to emulate. Depending on the value of this option, the correct
default pitch bend range is set.
A new MidiParser object is created every time a MIDI track is played, but the
old parser would not be freed. Fixed this by reusing the old parser instead of
creating a new one, which is more efficient anyway.
This removes the MidiPlayer from the Music class, because it relies on
MidiChannel objects which are not used by the Miles AdLib driver. This should
fix the volume control.
