Fair point :)
Alternate tunings/keys is something I’m interested in adding. I don’t know much about music theory (and surprisingly little about actual music boxes)—do you think it would be sufficient to add the other major and minor keys? Or should there be more fine grained control over which 18 notes are used for each song?
I think the ideal thing would be to let everyone choose all 18 notes on their own, yeah. With a C-major scale you can already get many of the most common modes just by transposing to a different tonic, but that doesn’t help with the ability to have chord progressions that go between modes (and also still doesn’t have any way of getting harmonic minor). Also having multiple adjacent half-step intervals is really useful.
