Ludwig is a songwriting tool that creates band arrangements for melodies or songs.

Ludwig uses artificial intelligence to write arrangements note per note, instead of relying on prearranged material. Ludwig mimics how a human creates band arrangements.

Ludwig tries to fit the arranged parts to a melody which leads to a more organic and less repetitive music than pattern-based band automats. Ludwig can create arrangements for a variety of small ensembles including string quartet, four-part choir, recorder trios, brass quintets and many more.

To use, simply enter the notes of the melodies and lyrics in notation or simply play them via MIDI controller. Ludwig can display the full score of the band or orchestra arrangement once its done and can do MIDI Im/Export and MP3-rendering, as well as MusicXML Export.
