Melodee FM-1 is GPL-3.0-only; what was copied is here under MPL-2.0 (each file's licence line rewritten, its copyright lines kept), as its authors allow: - Kerem Kilic's own code (Melodee's UI and its design are his). - Leo Kuroshita's Felucca code that Melodee FM-1 keeps (each file's header says where), and `fm1/assets/icons.json`, the icons' names, his: "Anyone may use the Felucca code for which I personally hold the copyright under MPL-2.0" (Leo Kuroshita, hugelton/felucca-bsp#4), with his name in the credits: Leo Kuroshita (@kurogedelic), Hügelton Instruments. - No other contributor's lines: the sync checked every copied line (`git blame`) and rewrote another author's (the remote's own code: the USB HOST lines left out, the header's room for its pills, the knob acceleration, the nearest microtonal degree). Every change since is Kerem Kilic's. - No other people's code or data: the files that port other projects (FM6's Dexed and MSFA, SID's reSID, the 909's 9W9, SLOOP's effects, CrispyZebra, DaisySP, Rings, MAME's uPD933) and the factory data (Casio's CZ-1 tones, Sequential's Prophet programs) are never copied, and `gen_tables.py` comes without its reSID and FM6 tables. The remote has no engine: where Melodee FM-1's pages name one, `app/unit/` answers that it is absent. A few pure functions of files the remote leaves out (the keys' layout, the song's rows, a take's notes, the matrix's names) are copied as they are into `fm1/src/excerpt_*.c`, under the same checks. Melodee FM-1's own copies stay GPL-3.0-only there. ## From Saadet The remote takes its platform from Saadet's fm1-base port, and only Kerem Kilic's own code from it: - `tools/build_base.py` follows Saadet's `tools/build_base.py` (the pinned fetch, the disposable copy). - `tools/base_overlay.py` carries, from Saadet's `tools/base_overlay.py`, its `replace` and `function` helpers and its peripheral-link changes to fm1-base (timer routing, fresh-link state, the subscription bit, GAP name reads, Bluetooth off while starting). The SysEx and naming changes are new. - `app/app.h` keeps Saadet's splash colour and its panel-calibration store offset. - `web/install/` is Saadet's web installer (MPL-2.0 there too) with Melodee Remote's words: Kerem Kilic's code, with the portions it keeps from fm1-base's `web/installer.html` and `fm1ota.js`/`fm1pkg.js` (Charles Vestal, Leo Kuroshita) under MPL-2.0 as fm1-base gives them; `web/test_install.mjs` is its test. - `tools/make_site.py`, `tools/release_support.py`, `tools/prepare_public_release.py` and `tests/site_test.py` follow Saadet's. Saadet's `make_site.py` and `site_test.py` are GPL-3.0-only there; they are Kerem Kilic's alone, and here he licenses them MPL-2.0. Nothing of Saadet's instrument is here: no engines, no factory sound data (Roland's, Sequential's, Casio's), no Felucca-derived UI or editor code, and none of Saadet's GPL-3.0-only web pages (its editor and manual). ## Changes to fm1-base The overlay changes fm1-base's MPL-2.0 files `ble/midi/le_midi.c`, `ble/shim/systimer.c`, `device/radio.c`, `device/plat_fm1.c`, `host/plat_host.c`, `include/plat.h` and felucca-bsp's `chip/usb.c` (USB's SysEx to the app a byte at a time) and `boards/fm1/fm1_input.h` (the light levels) in the build copy. The changes are MPL-2.0 and published here, in `tools/base_overlay.py`; the changed files keep their notices and add a line crediting the change.
