The file types MIDI (.mid), Karaoke (.kar), MusicXML (.mxl, .musicxml, .xml), and NoteSoft (.not) are all supported by notation software. They will create sheet music with lyrics from the MIDI and Karaoke files (if any). When using a notation software package, NoteSoft files are those that are produced. Wav, MP3, and other file formats cannot be opened by notation software.
