This is my first Eurorack module clone from a Mutable Instruments module, where I had to solder the Microcontroller.
But it was worth the effort, as I can also make use of the the latest firmware update v1.2 with all the new synthesis models and the ability to load DX7 patches.

I shared some more details about the SMD soldering process and the programming.

All details are available on GitHub, including the .hex files for the version v1.1.

I hope, this also helps others to build their own version.
Let me know in the comments, if you have any question about the build.

Enjoy.
