Description
Drop your own OS file onto the page, which identifies it by sha256, builds the chosen mods in a WebAssembly worker using elektron-firmware-tool, and only offers the result if it verifies. Hardware reports are the author's own: MK1 builds have run, Keys builds have run, and no MKII build has ever been run on an MKII. Rytm MK1 and MKII are listed here; the Analog Keys features are described under the analog-keys entry. The repo says the mods never change the recovery code.
Install notes
Flash a Control build first, then add one mod at a time. Elektron now serves only OS 1.74 for Rytm; a unit on 1.74 cannot take these files and going back is unverified. Recovery uses the startup menu over DIN MIDI.
