Logical Editor

The Logical Editor is a powerful tool for search and replace functions on MIDI data.


The Logical Editor is only available in Cubase Pro. However, the Transformer MIDI insert and the Input Transformer that share many of the functions with the Logical Editor are also available in Cubase Artist.

The principle of the Logical Editor is this:

  • You set up filter conditions to find certain elements.

    This can be elements of a certain type, with certain attributes or values or on certain positions, in any combination. You can combine any number of filter conditions and make composite conditions using And/Or operators.

  • You select the basic function to be performed.

    The options include Transform, for changing properties of the found elements, Delete, for removing the elements, Insert, for adding new elements based on the found positions of other elements, and more.

  • You set up a list of actions, which specify exactly what is done.

    This is not necessary for all functions.

By combining filter conditions, functions and the specific actions, you can perform very powerful processing.

To master the Logical Editor, you need some knowledge about how MIDI messages are structured. However, the Logical Editor also comes with a rich selection of presets, allowing you to access its processing powers without delving into its more complicated aspects.


Studying the included presets or using them as starting points to set up your own actions is an excellent way to learn the workings of the Logical Editor.
