Mathematics software

• Continued Fraction Calculator
• Fast Decimal to Fraction Approximations
• Fraction Calculator — An Android app that User:PiotrGrochowski recommends to install. Allows to do arithmetic on fractions, while not outputting a mixed fraction.
• Fraction Expression Calculator - easily do ratio arithmetic
• Least Common Denominator of Fractions (LCD) Calculator - put your JI ratios in here!
• Number To Fractions — Finds fractions to a number that improve over the previous. Allows restricting to 3–limit, 5–limit, 7–limit, 11–limit or 13–limit. Type a number to be approximated by JI ratios, or the binary logarithm of a ratio to be approximated by edo intervals.
• Octave - a free, open source equivalent to MATLAB; useful for working with matrices and much more
• Online LaTeX Equation Editor - create mathematical expressions in LaTeX format for wiki pages etc.
• Wolfram Alpha - perform a variety of intensive mathematical calculations in your browser

Notation software

• abcm2ps Free, open-source, ASCII-based editor with support for some microtonal accidentals.
• Lilypond Free, open-source, outstanding notation software that produces beautiful engraving-quality output on a par with commercial applications like Sibelius. Thanks to the work of Graham Breed, can use Sagittal glyphs. With the Ekmelily extension, it can support several other notation styles, namely Tartini, Richter Herf/Madel and Sims.
• MaxScore is an Java object for Max/MSP. It is based on Nick Didkovsky's JMSL which natively supports quarter-tone notation, but is capable of playing back microtonal music with unlimited precision. In the most recent version of MaxScore, microMaps have been implemented in the score canvas that allow the display of microtonal inflections in any kind of notation system provided that a font exists to represent those inflections. So far, microMaps for 48TET and 72TET exist. It is planned to develop an standalone editor which doesn't require any Max programming expertise. For more information send an email to [email protected]
• Mus2 is a microtonal score editor with intonationally-correct playback. It allows the retuning of staves and import of symbols from graphics files and fonts to be used as accidentals.
  • Dorico, expensive but a leading notation software with full support with the same method as Mus2 above. https://www.youtube.com/watch?v=zaadFpqm3-U
• MuseScore open-source notation software. Can be microtuned with the retuner plugin for almost any edo. The Xentuner plugin by Keenan Pepper is also very good. See MuseScore for the dedicated page.
