One writer, two engines

The song engine sets lyrics: it reads the form of your text and writes a sung, dark, electronic pop song in one of twelve families. The track engine reads a brief and builds an instrumental-first electronic track in one of 103 styles, bar by bar.

Pick a family and you get a song, pick a style and you get a track, whatever the text. On Auto the text decides: two or more stanzas, or six lines and more, read as lyrics; a single short block reads as a brief. Arc and vocal options belong to one engine each; the writer offers the ones of the engine at work, and the knobs that only one engine reads show while that engine writes.
