40 The space taken by a note is determined by the formula
42 arithmetic_multiplier * ( c + log2 (time) ))
44 where code(time) is the amount of time a note occupies. The value
45 of code(c) is chosen such that the smallest space within a measure is
46 arithmetic_basicspace. The smallest space is the one following the
47 shortest note in the measure. Typically arithmetic_basicspace is set
