Its source is https://github.com/chadthornton/usb-midi-host. This project includes, or is built from, the third-party work below. The firmware on the installer site (site/firmware/) is compiled from this repository together with the libraries marked "in the firmware". Not included anywhere: M-VAVE's FM-1 firmware images and JieLi's wl82loader.bin. The tests download them at test time (tools/fetch_fixtures.py, pinned by SHA-256, into the gitignored tests/fixtures/), and tools/build_site.py refuses to publish wl82loader.bin or any piece of it.

SIL Open Font License 1.1: https://openfontlicense.org/open-font-license-official-text/ Ported into this repository --------------------------- MvaveFM1Unbricker, https://github.com/Quixotic7/MvaveFM1Unbricker (in the firmware) Copyright (c) 2026 Michael P Jones. MIT License (text below). Ported: the softkey handshake (lib/fm1_loader/src/softkey.*), the .fwsc/UFW package parsing (lib/fm1_loader/src/package.*, tools/fm1lib.py, tools/catalog_dedupe.py), part of lib/fm1_loader/src/crypto.*, and the test mock (tests/support/mock_rom.*). The Unbricker's package parsing, CRC and header cipher say they are ports of firmware/src/ota.c in Felucca (https://github.com/hugelton/Felucca), which derives from M-VAVE's fm1_open; both are GPL-3.0. See docs/public-release-audit.md, "Licenses". Outrigger as a whole is GPL-3.0, which settles that question. jl-uboot-tool, https://github.com/kagaimiq/jl-uboot-tool (in the firmware) Copyright (c) 2023 Andrey Grigoryev (kagaimiq). MIT License (text below). Ported: the ROM-boot command layouts (lib/fm1_loader/src/rom.*) and the MengLi cipher and CRC (lib/fm1_loader/src/crypto.*).
