Only a user error, in fact I didn’t give a name to the project… duh.
I remember a démo @ modularsquare he named a project with aaa or ccc and it saved and reloaded perfectly.
Otherwise, on my first use of the hermod i saved à project with à long name (with the date and a name maybe 15 characters) and that froze the unit.
I cannot reload this project either. Made this two more times with the same issue.
Since that, i name my projects with les that 8 characters and works fine.
A little thing that annoy me is that when you save, it takes a little time that make loose the clock to other gears connected (ex trigger Riot)
I haven’t upgraded to is 1.01 yet.
Maybe the issue is solved
