- Structural Arranger, Style, and Vocal Timbre: - Three preset song layouts, or add, reorder and size each section in bars. - A colored timeline bar shows when each section starts, worked out from the BPM. - Genre and mood buttons (you can add your own) and a BPM slider. - Four voice cards: Baritone, Alto, Spoken Word and Vocoder. - Lyrics: One-click Vocal Stutter, Glitch Chop and Vinyl Crackle buttons drop the tag in wherever your cursor is. The break line tool lets you pick dotted or dashed lines and a label, then insert a line at the cursor, between all stanzas at once, or with the "+ Break" buttons in the stanza preview next to the editor. - Meta Tags: Weirdness and Style Influence sliders, a list of styles to exclude, and a model choice for MusicAPI. - Sovereign Master Export: A Suno tab with copy buttons and character counts for each field, a MusicAPI tab with a ready-to-send request, and a full master sheet you can copy or download as a text file. When "Map stanzas to arrangement" is on, it fills your stanzas into the song's sections in order and labels the intro, breaks and outro with their bar counts and notes. How it saves: Your work is saved in your browser, so no account is needed. The flip side is that it doesn't sync between devices. For MusicAPI, I used the newest model names from their current docs (Sonic v6). I tested the step that builds the final text, and all those checks pass.
