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.) | By default, the mode for which nominals are applied is the symmetric mode, corresponding to a UDP of n<nowiki>|</nowiki>n.

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. | 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). | Alterations refer to raising scale degrees by a chroma beyond the large and small sizes of a mos.
