Custom Allotment Libraries
The allotment configuration installed in the Finale
Default File included with TempiFont and
ThesisFont employs a spacing algorithm which generates
a reasonable horizontal layout of entries in most cases. However, circumstances
are likely to arise where alternate spacings are desired.
The parametric equation used to generate the Default File's allotments employs
a scaling factor, Q, which determines the degree to which entries larger
and smaller than a quarter-note are related to the quarter's allotment. When
Q=0, the allotment table is proportional -- a half-note occupying twice the
space of a quarter; an eighth-note occupying half that of a quarter. As Q
increases from 0, the allotment table becomes increasingly compressed, with
larger note values occupying less space and smaller durations given
proportionately more space.
When Q=0.3 the allotment table is that of the standard spacing table of the
Default File. When Q=1, the allotment table maps all durations to a single
value. In all cases the tables are calibrated about a standard allotment
of quarter-note=148 edus. Allotments of 63 durations each are provided for
Q = 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6 and
Q = 1.0 -- 14 sets in all.
The example linked to this paragraph documents the effect of various allotment
libraries on an excerpt from the bassoon part to the third movement of
Beethoven's Sixth Symphony. Click on the example to download a PostScript
