Tartini, Richter Herf/Madel and Sims
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.
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.
