Since you mentioned the music, I’m actually planning on redoing/replacing the music later so I’m hoping people don’t get too attached to it. But I’m glad you like what I have so far.
I had this on a Mac too (macOS Monterey, Mac mini 2018) and it wasn’t saving files either. I tried downloading the latest version and I’m getting a pop-up saying ”‘ChipTone.app’ is damaged and can’t be opened.”
