What changed from 0.2.3: the FM-1 on its own

Without a host, RemoteFM1 is now an instrument of its own (the full control map: README.md "Standalone",
STANDALONE-PLAN.md section 3). A host's SESSION still takes it over as its panel, exactly as in 0.2.

• A DX7. saadet's FM6 engine (Kerem Kilic; MSFA's DX7 maths, sample for sample as saadet renders it), 8 voices
  over the FM-1's two cores. Yamaha's 8 ROM cartridges (256 voices) built in; send your own 32-voice cartridges over
  SysEx (up to 3 user banks). PRESETS the voice (rolling into the next cartridge), GLO + SELECT the cartridge.
• Playing. Velocity keys, OCT-/OCT+ (both: panic), scales that snap the keys (GLO + PRESETS the root,
  GLO + ALGORITHM the scale), LATCH (hold LFO), an arp (tap / hold ARP), SELECT the tempo, MIDI clock in.
• A looper. REC records exactly what you play, from the first note; 16 loops on SEQ (white keys pick, launch
  instantly, at the bar or at the end); count-in and a metronome; save / load over SysEx.
• A MIDI controller. Notes and 5 banks of 4 CCs out over USB and Bluetooth at once; MIDI in from USB, Bluetooth
  and the TRS jack plays the DX7. REMOTE MIDI (GLO + FX): every key, button and knob just sends MIDI, with its
  own settings page (hold HOME): screen, absolute / relative knobs, channels, keys, octave keys, scale shortcuts,
  knob LEDs.
• Looks. A pixel-art UI with 9 themes and background colours (SAVE), Notes / Scope / Keys views (HOME).
• For hosts. The TRS jack's MIDI goes to the host's firmware during a session (MIDI_IN, 0x54; caps bit 9). A
  bare HELLO no longer hands the unit over: only a SESSION start does.
• Settings live only in 0xF2000..0xF3FFF (and user banks in 0x93000..0x96FFF), where no other FM-1 firmware keeps
  data; Bluetooth pairing is now saved too.

Testing

On an FM-1 on 2026-10-30: the release package installed as FM-1_52000300; the DX7's render hash on the unit equals
the computer's on one and two cores; macOS shows the FM-1's USB audio devices; the owner played it, MIDI over USB,
Bluetooth and TRS (an OMX-27), and the website with FIZZ getting the TRS jack's MIDI. The simulator suite (every
standalone feature), the site, installer and remote-link tests pass.
