this was a topic here in 2005, but for me the issue never has been solved. I have been using Voxengo's WindowsVSTs in a special version of Ardour on Linux for many years, but it caused my many crashes, quite some wrinkles, plenty of gray hair. Consequently, I quit using Voxengo products recently and bought the rather expensive plugin suite from Harrison Consoles.
Hence I quit the crashes, but I can't quit the moaning, I'm just missing my Elephant too much.
So, once more, I ask for native Linux versions of the Voxengo product line. I think, the market is evolving and there are not many competitors. Most of them cannot offer what Voxengo can offer. With Ardour, there is a very good DAW available... and a native version of Reaper might soon be there on Linux.
I'm running the Windows version of the Voxengo plugins on Linux with LinVst.
Works very well with Reaper and other native Linux hosts.
I got all Voxengo plugins running in Linux (Linux Mint 18) using linvst (the simplest solution so far) and wine-staging. I start using some of them (learning curve) w/o any problems at all EXCEPT that inter-process communication is not possible since linvst starts a new process for each plugin. This means that the nifty export/import feature does not work (eg. GlissEQ). I'll take a look at the Carla host soon and will report back. I'm also writing down a clear procedure to run the Voxengo plugins on Linux, and will post it soon.
If any are wondering if my use of plugins is only hobbyist, well, I do not make money with music but I do actively make quite a few projects while still learning about mixing and all that, many ranging from 35 to 45 tracks at mixdown. I use the Voxengo plugins in Bitwig for creation and in Mixbus32C for mixing/mastering. As an example, here are two pieces:
Meanwhile I also use Voxengo Elephant via LinVST. Since this only worked well with the current version, I had to buy a new license. Which is OK, but for the other Voxengo plugins, I use alternatives now. There's some native ones from Harrison that work well, so I bought those. GlissEQ might be the one I would want to use in LinVST, too, in the future.
I tried Carla and vsthost (command line) but they could not run the Voxengo stuff in a stable manner.
