The bool column

By clicking 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:

  • If 2 condition lines are combined with a boolean And, both conditions must be fulfilled for an element to be found.

    Figure: The Logical Editor will only find elements that are notes and start at the beginning of the third bar.

  • If 2 condition lines are combined with a boolean Or, one of the conditions (or both) must be fulfilled for an element to be found.

    Figure: The Logical Editor will 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).bar.

When you add a new condition line, the boolean setting defaults to And. Therefore, if all you want to do is set up 2 or more conditions that all must be met for an element to be found, you do not have to think about the boolean column – just add the required lines and make the usual filter settings.
