Thanks for the nice words!
What song length do you think would be appropriate? My main goal here is to capture the charm of physical music boxes in this style and I feel like the current lenghts (between 20–120 notes) is a fairly good sweet spot. (In the initial release it was fixed to 48 which was arguably a bit too limited I think.) This already involves significant “cheating” for the rendering of the turning cylinder as there couldn’t be enough physical space for all these notes.
