5.3.8 Deleting Groups
Deleting a Group will remove it from the Group List.
It is not possible to have a Project without any Groups; attempting to delete the last remaining
Group in a Project will simply reset the Group to the default values.
You can select multiple Groups to delete them all at once! See ↑ 5.1.3, Selecting Multiple Sounds
or Groups for more information.
► To delete a Group, select it in the Group List and press [Del] on your computer keyboard.
You can also right-click (on macOS: [Ctrl]-click) the Group in the Group List or the Group
name in the top left corner of the Pattern Editor and choose
Delete from the context
menu.
→ The Group is removed. All following Group are shifted up in the Group List to fill the gap.
If the last Group bank is empty after the Groups have been shifted, the bank is deleted.
