Note Expression offers a very intuitive way of controller editing in Cubase. As an alternative to working with controller lanes in the Key Editor, controller data can be viewed and edited directly on the associated MIDI note events in the event display.

With Note Expression, a note and its associated controller data are treated as a unit. When you quantize, move, copy, duplicate, or delete notes, all their associated controller information will follow. This allows for a very intuitive and accurate editing of note-related data. The Note Expression values can be edited in various ways. Furthermore, by superimposing the corresponding data curves in the event display, you can view all the Note Expression data for a note simultaneously, which gives you a good overview.

When working with Note Expression, it is important to distinguish between VST 3 controllers and MIDI controllers.
