Hello seh52,
[Topic moved here.]
There's no officially-supported way to do that, I'm afraid (although we do have enhancement requests logged for more comprehensive sortable/editable names/browsers for organs, temperaments and combinations).
Unofficially (at your own risk), it's technically possible to rename the files using the operating system's file browser within your .../Hauptwerk/HauptwerkSampleSetsAndComponents/OrganDefinitions folder. However, be aware that if you were to do that then:
- Any subsequent updates/patches installed for the sample set would no longer overwrite/update your current version of the organ definition, so you would also need to delete your current organ definition, then, once installed via Hauptwerk's component installer, rename any such organ definition updates manually.
- The organ's sample set cache will be regenerated when you next load it.
- Any entries for that particular organ that you might have assigned to the 'favourites' list, or on the most-recently-loaded organs list, will no longer work.
