38 arithmetic_multiplier * ( c + log2 (time) ))
40 where code(time) is the amount of time a note occupies. The value
41 of code(c) is chosen such that the smallest space within a measure is
42 arithmetic_basicspace. The smallest space is the one following the
43 shortest note in the measure. Typically arithmetic_basicspace is set
