I upgraded my computer recently and reinstalled Studio One 2, Komplete 11 (with Kontakt 5, Battery 4 and so much more), and the many third part VSTs that I have that work in Kontakt.
I have tried to all the libraries by going to:
Studio One/Options/Locations/Instrument Library/Add
I have tried directing it to several locations, Adding, Applying, Refreshing and restarting several times.
Today I tried directing it to search my entire C drive. I got a warning that it could be a slow process, and went ahead. The result? Nothing. No instruments were added. *I am having the same issue with effects as well.
The only non-Studio One programs that have showed up since I installed Studio One on this computer are Melodyne (which came with my version of Studio One) and Native Instruments Reaktor 5.
I am dying to use my Kontakt 5, Maschine, and wonderful effects that I have obtained over the years (and used easily with Studio One on my old computer).
