MIDI Converter Studio converts MIDI files into popular audio formats, like MP3, WAV, WMA, or OGG Vorbis. These formats support meta information which helps to organize files in a collection, or easily search for a specific entry (name of album, artist, title etc.). If converting a bunch of related files (the same artist, album etc.), you can supply them with this data.
Just add the files to conversion list and fill in the fields that are common to all files.
The information will be added to every output file.
