It would be great to have the ability to solo the active instrument from within the Key Editor when editing multiple parts . Sometimes I have multiple events on the same note and need to identify which instrument is problematic and, as it is, I need to move them all to different pitches before moving them back once I have fixed the issue. Or close the Key Editor and do this in Project View.
If I could ‘Solo Active Part Only’ then I could identify the problem without leaving the Key Editor.
Here’s a post requesting the same.
