MC Musiceditor is free/open source (GPLv2) music notation software (Windows). It has been developed with only one purpose: to make life of musicians easier when making scores. This results in a userfriendly editor which makes professional scores without requiring specific knowledge (other than musical basics)! In short: MC Musiceditor is the easiest way to write, refine, hear and print professional scores.
MC Musiceditor uses a modification of the ABC-language which was invented by Chris Walshaw. The ABC language is simple to use and can create music scores from basic melodies to a complex symphony score. Our modification of the ABC-language makes it, in our opinion, all easier (why? Part 1 - Part 2). More Info »
For the convenience of ABC-users, MC Musiceditor 6.0.9 and later is a hybrid version: you can use the MC Musiceditor for MCM-code (default) and ABC-code! The trigger is L:mcm_default. If found, the code will be interpreted as MCM. If L: value doesn't equal to 'mcm_default', the code will be interpreted as ABC.
