Dear friends, I'm proud to share my midi expander project (I would apologize in advance for the naivety of my code)
https://github.com/SandroGrassia/Lilla-midi-expander

I would say thank you to Paul and to all many friends who gave me support, tips, and energy in the last 2 years (since this project started).
In a month I should be able to do a video with some musicians friends... In the meanwhile hope to find the time to do a video-demo.
