Figure A.2: Visualization of quantized chromagram bins over time from reference melody (left),
generated music conditioned on chroma and text (middle) and generated music with text-only
conditioning (right). Each row is generated using a different chroma condition, all rows share the
same text condition: “90s rock song with electric guitar and heavy drums”. We observe strong
adherence to the input melody for the music samples generated with chroma conditioning while
rendering novel styles guided by the input text.
