There are several ways to erase content on the EP-133:

Erase a pattern (quick erase): 1. Select the group with the pattern you want to erase (A, B, C, or D) 2. Hold shift + press erase 3. This clears the pattern for that group only

Erase while recording: 1. While in record mode, hold erase 2. Press the pads whose notes you want to remove 3. Notes are removed in real-time as the pattern plays

Erase a scene: 1. Navigate to the scene you want to clear 2. Hold shift + hold main 3. The scene content is erased (becomes blank)

Erase a project: 1. Hold shift + hold the project number pad 2. Confirm the deletion 3. This removes all patterns, scenes, and samples in that project

Important notes:

  • Erasing patterns doesn't delete the sounds assigned to pads
  • Erasing a project deletes samples too
  • There's no undo, so commit/save before erasing
  • Samples in the library persist unless manually deleted
