LCD-4 0.1.2

• Fixed: safe mode can be reached over USB again after a crash. If the FM-1 crashed while it was making sound,
  safe mode came up with USB off, so neither the web installer nor M-UPGRADE could find it until it was switched
  off and on. (The same fix as SEQ-4 0.1.0's; tried on an FM-1: two crashes on purpose, safe mode, then an install
  from it.) Nothing else changes.

Install

• From the browser (Chrome or Edge, the FM-1 on USB): the web installer. Or try it in the browser first.
• From the command line: python3 tools/fm1_install.py lcd4-0.1.2.fwsc (Python 3 with pip3 install mido python-rtmidi).
• Going back: the installer's "Back to the stock firmware", or M-VAVE's M-UPGRADE.

The firmware is lcd4-0.1.2.fwsc below; its source is this tag. Installing other firmware is at your own risk; see the manual's Troubleshooting.

LCD-4 0.1.1

• Fixed: the panel under the screen redraws when a track is muted or unmuted, or another track or drum
  part is picked. After a change of page it could keep showing the old state until a knob was turned.

LCD-4 0.1.0

The first release.

• Four tracks: a drum track and three synth tracks, each with its own sound, level, pan and sends.
• Drums: four kits of eleven parts (808, 909, Arcade, Box), the black keys picking the part and the white
  keys its steps, with tune, decay, tone and level for every part.
• Sixteen synth sounds modelled on their originals' circuits: Acid (TB-303), Mono (SH-101), Fat
  (Minimoog), Boom (808 bass), FM bass (DX7), Reese, Poly (Juno-60 and its chorus), Brass (Prophet-5 / OB-Xa),
  E.Piano (DX7), Organ (M1), Strings (Solina and its ensemble), Bells (DX / PPG), Sync, Scream (MS-20),
  Arcade (NES / Game Boy) and Arp (chip arpeggios).
• Patterns: sixteen 16-step patterns holding all four tracks, chains of up to 64, copy and clear, a length
  for each pattern, swing.
• Writing: live while playing (notes, chords, lengths, slides, accents, drum hits, knob moves, effects), step
  by step while stopped, and on the steps: a step held for its note, length and two locked knobs; slides,
  ratchets and accents.
• Chords: sixteen chords and chains of them, a chord a pattern; each synth track follows them or not.
• Sixteen punch-in effects, held or written onto the steps; a ping-pong delay, a plate reverb and a bus
  compressor.
• The screen: an LCD with a little game for every sound and kit, its segments lit by the music.
• Four demo songs (Pocket, Arcade, House, Lo-fi), the first one there on the first start.
• MIDI: notes in on channels 1–4 (the drums as General MIDI), clock in and out, notes out.
• Measured on the FM-1: the first demo takes about a quarter of its time; three tracks of four-note chords with
  every drum on every step stay under four fifths, and a governor thins the chords if it ever gets closer.
