Is it possible: still see locked midi track in editor?

Hi,
I’m editing a midi track that needs to conform, somewhat, to another midi track.
I’d like to lock the main track but view it in the editor while editing the secord track. First one acts as a reference.
But when I lock the first track it, kind of unsurprisingly, doesn’t display in the editor.
Is there a workaround for this?

Would temporarily unlocking the Track create a problem? If not that’s what I’d do. If it did I’d copy the Track and unlock the copy.
