Bool Column
In the bool column to the right in the list, you can select a boolean operator: And or Or.
A boolean operator combines 2 condition lines and determines the result in the following way:
-
And determines that both conditions must be fulfilled for an element to be found.
-
Or determines that at least one of the conditions must be fulfilled for an element to be found.
Important
When you add a new condition line, its boolean setting default is And.
Example
You can find elements that are notes and start at the beginning of the third bar.

You can find all events that are notes (regardless of their position) and all events starting at the beginning of the third bar (regardless of their type).
