Hello, This is MUSIA.
When changing the project key in Musia One Basic mode, the generated MIDI notes are automatically transposed. Please refer to the update details below.

[MUSIA ONE Basic]
- When changing the project key, all generated MIDI notes are automatically transposed to the new key.
- If the key is changed from “C” to “D”, the pitch of all MIDI notes will be shifted as much as the key changes from “C” to “D”.
- When changing from Major to Minor or from Minor to Major, the existing chord progression will no longer be deleted and will be transposed.
- If the key is changed to a relative key, the existing chord progression will be maintained as is.

We will provide more diverse features and content through continuous updates.
Thank you.
