=== Using a different step ratio ===


==== Using a different step ratio ====
By default, cent and step values will be calculated for a step ratio of 2:1. A different step ratio can be entered as shown below. Up to 5 step ratios can be entered, written as p/q and with each ratio separated by semicolons.

A mos-prefix, if defined under TAMNAMS, is automatically added. For mosses outside of TAMNAMS that have a prefix, enter it as shown below.

By default, the mode for which nominals are applied is the symmetric mode, corresponding to a UDP of n<nowiki>|</nowiki>n. In the case of a mos with an even number of modes and therefore two "middle" modes (n+1<nowiki>|</nowiki>n and n<nowiki>|</nowiki>n+1), the brighter of the two is used as the default instead. Since some notation schemes may use a different mode as its "default", the UDP can be changed, as shown below. (Use a comma instead of the pipe <nowiki>|</nowiki> symbol.)

The template will attempt to use default notation with a default UDP if the keyword "Default" is entered. The default is standard notation on C (for 5L 2s) and diamond-mos for any nondiatonic mosses.

==== Adding JI ratios ====
JI ratios can be added by writing a semicolon-delimited list of entries, where each entry is an abbreviation for a scale degree, followed by a colon, followed by the JI ratio.

=== Showing alterations ===
==== Showing alterations ====
Alterations refer to raising scale degrees by a chroma beyond the large and small sizes of a mos. For the number of alterations added, an additional altered degree is shown from raising the large size of a scale degree and lowering the small size of a scale degree (or the perfect size for period, unison, and equaves).
