What you need
Your own stock OS file. The author removed the complete .syx files and is moving to a patch-based route through the patcher on junes.website.
Good to know
At the time of writing the repository holds only the notice and an empty changelog. Back up first, beta builds can be destructive. SONG slots 13 to 32 are removed and anything left there is corrupted on boot. Please don't share complete .syx files.

NOTICE
In light of Elektron's updated stance on custom firmware, and to be on the side of caution, I will not be uploading my firmwares as complete syx files anymore, and will be using a patcher approach going forward.
I kindly ask that people do not distribute my firmware as complete syx files going forward.
I will be removing syx files from my GitHub and website for the time being while I create a patcher, which I'm hoping to have ready in October as I'm really busy at the moment.
Thank you for your understanding 🙏

MANDATORY READING
-
Please backup your projects before updating. This custom firmware is a work in progress, so there will be bugs, regressions, etc. and your project data could be put at risk.
-
Beta builds may contain destructive changes from build to build. Therefore I strongly recommend against working on anything critical on beta builds. If you want to live on the edge, please carefully read the changelog before each update.
-
SONG slots 13-32 have been removed to make room for extended data. If you have anything on those slots, back them up first, or move them to slots 1-12. Any SONG data remaining in slots 13-32 will become corrupted on boot. Snapshot data stored on the +DRIVE is preserved, as long as you don't overwrite it while the custom firmware is installed.
BUG REPORTS
If you find a bug, please open an issue for it. Make sure to mention which firmware version you are using. It would also be great to provide steps to reproduce the issue, if known.
If you'd like to make a suggestion or feature request, feel free to open a discussion.
