NOTION Music Forum

Whatever I check the relevant checkbox or not, the system key is not transposed. I have to manually change this.

I don't really understand what you're saying. You're not able to transpose the keys when selecting "Transposed" under the "View" menu?

No no, under the Tools menu !
Say I want to transpose a second minor down, the notes are transposed but not the key, whatever I ckeck the option or not !

For some reason Notion won't transpose the initial key signature - only subsequent key changes. So you have to change it manually. (At least, in my experience. And I have a feeling this was discussed before and others said the same.)

So, it's a bug.
