Description
Forked from Melodee (keremimo), which is built on Felucca. The firmware identity changes to FM-1_971, version v0.0.1-1971. The retired engines keep their stored IDs, so older projects stay identifiable, and the older PHASE, VOICE, WHEEL, PHYS and NOISE engines stay selectable next to FM6, SID, the Prophet engine and the drum engine. The simulator under web/sim runs the firmware as a WASM AudioWorklet and is taken from the melodee-tess simulator. Commit messages treat the project as work in progress, and the README is still Melodee's, including its link to Melodee's installer. The GitHub description calls it generative ambient firmware, but the committed code does not add any generators yet. The repository ships the same wl82loader.bin recovery helper from JieLi's SDK as Melodee, and no M-VAVE .fwsc files.
Install notes
No releases are published, so build it with build.sh as described in BUILDING.md. The README points to Melodee's web installer, which installs Melodee rather than this fork. It inherits Melodee's flashing risk and its recovery paths (the installer's return to official V15, the USB recovery tool for a device stuck in ROM UBOOT).
