Nice chart @Thovy64
There is something I do not understand yet. The very first screen you start from (the pink looper mode screen) assumes an empty song AFAIU.
So what about that screen after a song has been stopped ? I feel like it would go against something you (we) actually have voted for but I am not completely sure. Can you clarify how you would see the thing regarding the solo restart within that scope ?
Another point, even if minor (and I definitely would not consider that as a showstopper), is the fact that the upper left switch is the only one which unfortunately has a “harcoded” name printed on the case which says “Play/stop All”… (@DavidPackouz in any case, even if this is not implemented, I would strongly suggest future batches of Aeros should not have this… preserving potential usage of the switch for something else… That way we will have collector Aeros by having it 
).
