In the meantime, I could help users tracyross, Fitsch and udr by providing them a new plug-in-manager component.
Now, I’d like to get a little more safe and make sure that my fix works also on other machines.
Therefore, is there anyone else still having trouble getting NotePerformer, Kontakt or other VST2 plug-in getting listed in Dorico?
Then please send a mail to ‘u dot stoermer at steinberg dot de’ with a short description of what your problem is.
If it is really that very same issue, then I can provide the new component plus instructions to you.
Thanks for attention.
