Pardon me but searching for “binding external (control) surface” does not result in any handle for me.
Either google or bing (& derivates) doesn’t prompt any occurance of F24+. Would it be possible for you to share any search result from your matching results so that I can familiarize myself with the -to me unknown- topic, please?
Otherwise I appreciate trying to recall, Sir/Madame!
Thanks, @kevincox@lemmy.ml. That sums up my options.
