After having to many issues trying to get lmms with VSTs to run natively on Fedora, I decided to install KXStudios in VirtualBox (With some more trouble, though it had nothing to do with lmms, I was forced to upgrade to KXStudios from Ubuntu 14.04 due to when trying to boot KXStudios it wouldn't boot correctly after changing Desktop Environments), Now i'm still having issues running VSTs in lmms, VeStige appears to be working, it opens normally, however when I try to open any of my VSTs it says "The VST plugin (Directory) could not load for some reason". I tried it with Synth1 and the same error occurs, what could be the cause/s and what are the solutions? I would think this should be working as it's a completely new KXStudios install. (I won't be able to respond to replies for a few days, so i'll read everything then and reply).
Have you installed WINE?

You can find hints to different distros and different WINE packs.
Let us know how it went
