Edit: I downloaded several Neural DSP versions (Archetype Nolly X, Archetype Gojira X, Archetype Cory Wong, Archetype Rabea and Mesa Boogie Mark IIC+ Suite) from the offical site and installed them on the regular path, but none of them show up in Studio One 3.
I already checked everything: the chosen path for vst's in S1 (C:\Program Files\Common Files\VST3), reset the blacklist, allow to check for new plugins, created a new folder and added it to the path and so on... I reinstalled it but with the same resultes.
Its definately a Studio One problem. I installed Reaper and everything worked perfect, so I erased Studio One and installed it again, but still nothing. The PreSonus support answer is, that Studio One 1-3 will not longer be supportet. So if I need help, I have to update for 150 $ to Studio One 6 - thats rediculous! A **** joke!
Where are the differences between Studio One 3 and Reaper 7?
Does anyone have any ideas as to what the problem could be or how to fix it? I really need help with that.
Thanks for all upcoming ideas.
