BME2, Braille Music Editor 2, is a new and extraordinary tool allowing blind musicians (amateurs or professionals) to write music scores, to check, to correct, to print or to emboss them all by themselves. Music writing follows the rules of the New International Manual of Braille Music Notation. The music score can be checked in various ways, through the screen-reader speech output pronouncing musical elements, through the MIDI sound or on the Braille display. Once the score is complete, it can be exported in MusicXML and visualised with Finale, Sibelius or lots of other programs, that are able to support this format and finally it can be exported in a ready-to-print text format or directly printed. BME2 is the evolution of the BME program, thanks to suggestions of expert users or people keen on music.
