I am neutral here - I don't know a thing about Moschino or Chromatic free bass. However, it is refreshing to see people passionate about their accordions - long may your Moschino make beautiful music.
Now, I do not really understand the Moschino system, despite having watched some Youtube videos about it.
However, I am convinced that all bass systems are of secondary importance to the dedication and talent of the musician. It is the man or woman who makes these instruments come to life - that's what shines through to me. The arrangement of notes is
nothing without the ingenuity of the human being!
As for the winner who was fighting with his weak chromatic system... He still won - just sayin'.
