music-skill 0.2.0

More styles, each with a guide written from its sources, a nylon-string guitar, and a way to see what a revision changed.

• Guides for more styles, each with its sources listed at its end: film score (underscore, scoring to picture, suspense and horror), pop and ballad, rock and metal, and baroque, plus boom bap and trap, techno, blues and bossa nova in the existing guides.

• A nylon-string classical guitar, iowa_guitar, cut from the University of Iowa's 2011 recordings: the thirtieth bank. fetch_soundbanks.py --only iowa_guitar installs it from soundbanks-1.

• studio.py compare shows what a revision changed between two renders:

  • the project's edits and the parts synthesized again;
  • for every stem, bus, reverb and delay return, the premix and the master: identical, or where it differs, in bars.

  --clip makes an old-then-new clip at equal loudness, and --differences writes each change on its own. Before and after shows it on a one-note revision.

• Reverb and delay returns as files on the bus chain. With the buses they add up to the premix, so a mix can be rebuilt in another program.

The example recordings on examples-1 are unchanged. The changelog has the details and the known issues.
