An .mtd file is used by MusicNotes Viewer software to display digital sheet music. The .midi file type contains music data for the playback of multiple instruments. The .mtd file can be converted to the .midi file type using MusicNotes Viewer.
Download, install, and run MusicNotes Viewer (free, see Resources section). This Windows compatible program is the only software which can create, open and view .mtd files.
Open the .mtd file you wish to convert.
Save the file as .midi. Choose this option from the File menu, and then specify the file name and location for the converted file.
- This program will only export noncopyright-protected .mtd files to .midi format.
