Maybe I should have been more specific - I copied the plexi 50 preset to #500. I want to delete the pre-existing scene four as I only would use the 3. I cleared all the blocks but it stays in list. In addition to eliminating Scene 4, how do I do the following seemingly very basic operations:
1) copy a scene: for example copy scene 2 to scene 5 in the same pre-set so I could modify or add an effect to the new scene.
2) edit the name of a scene
3) edit the name of a pre-set
You seem to have a fundamental misunderstanding of scenes.
Scenes control the on/off and channel selection of blocks only.
Any block in a preset is in all scenes. I'm not sure what you mean by "cleared all the blocks"... Bypassed them?
If you don't want the scene name to appear you can delete the name but the scene is still there.
Are you using FM3-EDIT? There are options for managing scenes, including copying and also editing the name.
