Late July: Undo, vocals, challenges, and collaboration

Late July expanded both the editing loop and the ways creators could participate together.

• Undo and redo made graph experimentation safer.

• Node grouping made larger arrangements easier to organize and move.

• Vocal Nodes and Songbook brought lyrics, pronunciation, pitch, intensity, and vocal mixing into the graph.

• Daily Gig added short creative puzzles with feedback and report cards.

• Weekly Battle of the Bands added persistent bands, briefs, private listening, voting, and results.
