Song Sketch
Sketch a whole song's FORM with a BAND. A Song node sets the structure — sections (Verse, Chorus) arranged Verse · Verse · Chorus · Verse, looping — and THREE sources FOLLOW it together: a Chord Progression (the harmony), a Piano Roll (the melody), and a Step Sequencer (the drums), each holding its OWN per-section pattern. Drop it and press play: the verse plays twice, the chorus lifts (a higher melody + a busier beat), then back to the verse — chords, tune, and drums switching section together. Edit each part with the section selector on its card (pick Verse, set its content; pick Chorus, set its own) and re-arrange the section blocks on the Song card (drag to reorder, double-click to repeat, + to add). This is the COMPOSITION layer — the patterns the whole patch follows — above the Arranger's audio/MIDI clips. A FUNCTIONAL preset (explicit nodes + connections); the drum Instrument auto-loads the GM kit on drop.
