Select the bars you want to keep, then optionally Generate opening before them or Generate continuation after them. Choose full for melody and harmony, or melody for freer accompaniment.Score properties: generated lets the model choose; locked lets you set tempo, meter, key, and unit note length; reference keeps the reference's properties. When using a reference, locked mode keeps its meter, key, and unit note length while allowing tempo changes. Generated properties with a reference require an opening.Song history: browse saved songs and Use as reference to reuse selected bars. Use saved score reuses the finished score as-is. Restore lyrics and style, the seed, or Restore all to recover the saved Score settings too. Older songs may lack those settings.Embedded songs: each saved FLAC embeds its final score with its workflow. Drop the FLAC into ComfyUI to see the score again, or use Embed YuE2 Kit song to carry the song's settings into other workflows. The YuE2 Kit - Embedded song demo template uses it to add a visualizer to a saved song.Base / Instrumental: each tab keeps its own lyrics and style. Instrumental also selects the instrumental AR LoRA. Use full score mode and <code>[instrumental]</code> or lowercase section tags such as <code>[intro]</code>, <code>[verse]</code>, and <code>[chorus]</code> on separate lines, without sung words.NAR LoRA: an optional acoustic adapter. Start at strength 1.0; select (none) or strength 0 to disable it. Use the ComfyUI export.Score playback: add <a target="_blank" rel="ugc" href="https://github.com/mrbumpy409/GeneralUser-GS">GeneralUser GS</a> or another General MIDI <code>.sf2</code> to <code>models/soundfonts/</code>. Notation works without a soundfont.Visualizer video: enable it and choose a still, or use the supplied artwork. The image sets the video resolution.

YuE2 Kit - Song workflow

Embed YuE2 Kit song carries a FLAC's settings into other workflows, and the Embedded song demo template uses it to add a visualizer to a saved song. Final outputs now saves the final score inside the FLAC's workflow and shows it on the node. Song history prefers it over the .abc file. Optionally write the title, artist, lyrics, style, BPM and key into the FLAC for music players.
