The bit.ly link to the user manual for Spitfire Audio's templates is not working... Perhaps its my browser. Does anyone have a full length version of the link?!
AFAIK, the https://www.spitfireaudiothepage.com/templates page is being merged into this forum, via the 'Making Music' category.
This post from @Angus might explain where these are. Hope this helps!
As for user manuals, I did a quick Google search and found the ones for BBC SO via https://www.spitfireaudio.com/manuals-archive/bbc-sy…
Was there a manual for a particular library you're looking for?
