Show Note Numbers
When enabled, the trigger or control will show the MIDI note number in addition to the mapping name or note name.
This also affects the notepicker in a similar fashion.
Using this feature is a matter of personal taste. If you prefer to only see the mapping names (e.g. kick, snare, ...) then leave the note numbers off. If you're more of a MIDI purist and prefer to see the note numbers (e.g. 36, 38) then enable it. It does not affect your SysEx in any way, only the display or triggers.
Note that even when disabled, ZenEdit will still display note numbers in some situations if there is not a suitable mapping name available to display.
