BOP-1 0.1.0

The first release: a music and synthesis toy for children, on the M-VAVE FM-1.

• Four doors: Play (3+: music at power-on, the keys in the scale, the knobs change a friend you can see,
  Surprise!, magic tricks, Loop me), Make (6–8: four layers, sixteen steps, recording in time, help me, parts
  A–D into a song, happy / sad / brave / sleepy chords), Lab (9+: a real subtractive synth by its real names,
  a signal-flow picture, a live scope, My Friends) and Games (six games and a sticker book).
• Eight friends whose bodies are the sound: the waveform their shape, the cutoff their mouth, the envelope
  their hop, the LFO their wobble, the pitch their size, the echo their place.
• A song generator: eight styles, four progressions, a call-and-answer tune that comes home; the same seed
  always the same song.
• Ten lessons with try-its the firmware checks; printable lesson cards for a class.
• The grown-ups' page (GLO + SAVE, 3 s): the doors shown, the volume cap, calm lights, the screen, a sleep
  timer, idle, music at power-on, MIDI.
• Safety: an always-on limiter under the volume cap; no squeals in Play and Make; flashes at most three a
  second (none when calm), measured by a test.
• Printables: a sticker overlay for the buttons and knobs, the lesson cards, a quick guide, a picture
  quick-start. A browser emulator, a web installer, a manual.

Install
