28 The space taken by a note is determined by the formula
30 SPACE = arithmetic_multiplier * ( C + log2 (TIME) ))
32 where TIME is the amount of time a note occupies. The value of C is
33 chosen such that the smallest space within a measure is
34 arithmetic_basicspace:
36 C = arithmetic_basicspace - log2 (mininum (SHORTEST, 1/8))
38 The smallest space is the one following the shortest note in the
39 measure, or the space following a hypothetical 1/8 note. Typically
40 arithmetic_basicspace is set to a value so that the shortest note
41 takes about two noteheads of space (ie, is followed by a notehead of
44 2*quartwidth = arithmetic_multiplier * ( C + log2 (SHORTEST) ))
46 { using: C = arithmetic_basicspace - log2 (mininum (SHORTEST, 1/8)) }
47 { assuming: SHORTEST <= 1/8 }
49 = arithmetic_multiplier *
50 ( arithmetic_basicspace - log2 (SHORTEST) + log2 (SHORTEST) )
52 = arithmetic_multiplier * arithmetic_basicspace
54 { choose: arithmetic_multiplier = 0.9*quartwidth (why?)}
56 = 0.9*quartwidth * arithmetic_basicspace
60 arithmetic_basicspace = 2/0.9 = 2.2
