Solved! Erasing MIDI Data froom the Key Editor

Cubase
11

Thanks guys, figured it out with your help. If anyone else interested in this:

  1. Select all the MIDI Tracks and open them in the Editor and select all MIDI notes inside.
  2. In Logical Editor under Standard Set 2 presets select Del Patch Changes and Apply
    (this will delete everything except FX Depths) to do that:
  3. Keep everything highlighted, go to MIDI in the Menu, Functions and select Delete:
  4. All controllers…2. All continuous controllers.

The whole thing will be clean except Velocity which of course is not something you can delete.
