This driver was used in Commodore 64 games by unrelated companies with either unknown or unsourced audio credits.
In all songs, each note has a byte whose 4 LSBs stand for the instrument number and 2 more significant bits for modulation type (10hex = pitch bend up, 20hex = down, 30hex = vibrato). In most games, each note also has its own duration and modulation depth.
Unusually, in memory, a note is not followed by its properties, but a sequence of notes is followed by sequences of their properties.
