Moving to kontakt for higher quality
It's possible to use high-quality kontakt soundfonts on linux. For this you are to install airwave vst bridge, carla host plugin, wine. Then get kontakt player 5.3.0. Higher verions won't work on linux.
After installing all this you load kontakt player's vst into carla and load kontakt soundfonts into kontakt player from carla. I guess kxstudio linux already has all those installed.
You can use linux for professional grade quality production nowadays with the same features like on windows. And no viruses! + jackd better works on linux than on windows.
