to switch a large trigger out for a smaller one or vice-versa.Trigger Size
If you've customized the available triggers on your Zendrum then it is possible that the default size selected by ZenEdit does not match your personal instrument.
Use the trigger size control on the Customization Mode view icon to switch a large trigger out for a smaller one or vice-versa.
This setting only affects the look of your Zendrum in ZenEdit, and has no bearing on your SysEx settings.
