Is a lowlatency Linux kernel required to discover/load Windows VSTs? #733

Hey there, I'm totally new to audio production in Linux but after the initial setup I'm pretty blown away by some of the tools, including this one!

I've got almost everything more or less setup now including Jack, Cadence, Bitwig and Carla running Linux native plugins, but I'm having a bit of trouble getting Carla to discover and load my win64 plugins.

I have added my win64 plugin directory path to the Settings>Paths menu, and I've also installed the carla-bridge-win32 and carla-bridge-win64 packages from the official KXStudio repo. But there seems to be no change to the list of "available tools", and none of my win64 plugins are detected. Everything else appears to be working normally, so I suspect that it's because I'm running the "generic" kernel that came with my distro.

I've kind of shied away from using the linux-lowlatency kernel so far because this is my main desktop PC that I use for a variety of things (music, art, coding, browsing and gaming) and so far I've had very acceptable audio latency without it. (It's possible that using the lowlatency kernel wouldn't negatively effect those other tasks too much, but I've kind of been conservative about it since I'm new to this.)

So does Carla absolutely require a lowlatency/rt kernel in order to discover and load win64 VSTs? Or is there some other problem?

My specs: Ubuntu 18.04 (kernel 4.15.0-33-generic x86_64) AMD Ryzen 5 1600 16GB DDR4 RAM Focusrite Scarlett 6i6 USB Audio Interface PulseAudio/Jack/ALSA + Cadence 48000Hz@64samples (1.3ms latency)

Thank you for all your work on Linux audio. =]

There is no special requirement of kernel or system setup in order for Carla to work (or any other application, really)

The bridges are just considered experimental right now, so you will have to open Carla settings, enable experimental and then enable Wine bridges.

Let me know how that works for you. Thanks.

That worked! I made sure I was updated to the latest version and found those settings. Thanks falk!
