Amenity 2.1.1

Amenity 2.1.1 follows a MIDI clock over Bluetooth more reliably: it no longer
stops when the clock drops out for a moment, and it picks the clock up again in
time.

Install or update: https://ejtb76.github.io/amenity/ (Chrome or Edge, FM-1 on USB). Your own breaks and your settings stay.

Fixed

• Following a clock over Bluetooth no longer drops out. Each Bluetooth
  MIDI message carries the time it was sent, and one message with a wrong time
  (seen: 1.5 seconds off) could make Amenity think the clock had stopped, so
  the break went silent while the other side played on. Amenity now spots a
  wrong time and uses the moment the message arrived instead.
• A Stop from the device that leads always stops Amenity, also when its
  clock went quiet just before.
• After a short gap in the clock, the break is back in time at once.
  Before, when a few pulses went missing (under half a second), the break
  waited about as long as the gap and then ran behind the sender.

Changed

• When the clock stops without a Stop, the break plays on. A Bluetooth
  dropout or a computer that hangs no longer stops it: after half a second
  EXT turns orange, the screen says NO CLOCK: ON and the break carries
  on at the tempo it measured. When the clock comes back, Amenity picks it up
  where the sender is now, without a new Start. A Stop from the sender, a new
  Start or PLAY stops it. (In 2.1 the break stopped after half a second
  without clock and stayed silent until the next Start.)
  While Amenity plays on alone it sends no clock to the devices behind it
  (MIDI THRU): they wait for the clock to come back.

Updating from 2.1

• Install over 2.1 (or 2.0) from the page above; your own breaks, their
  order and your settings stay.
• Going back to stock (or another firmware) still erases your own breaks:
  keep your WAV files. Your settings stay and come back when you install
  Amenity again.
• Amenity 2.1.1's identity is FM-1_817020101 (pattern FM-1_817XXYYZZ).

Works on both FM-1 flash chips (Puya P25Q80 and UC25HQ80), as before.
