This is in no way comprehensive.

Native

Commercial

• u-he All work great in Linux.
• pianoteq Works great in Linux. I've used Pianoteq as the sound for my classical piano practice since v3. Back then, I could only get 64 sample latency under Linux, not Windows.
• renoise redux like with renoise, works great in Linux.
• Tracktion F-EM and Collective work (I have nothing else of theirs to try)

Free

• Surge XT
• Vital
• DSP56300 Emulations including Osirus and Ostirus
• Cardinal (Vcv-as-plugin Rack Fork) The paid tier of VCV has a VST plugin, but not the free one.

Wine

Using yabridge

• Xfer You need to disable d2d1.dll in winecfg and use winetricks gdiplus (see Wine Audio Plugin Notes)
• KV331 Synthmaster Plugins
• Some Arturia (including Pigments)). I'll try other ones out when I have the chance. I have V Collections 3, 6 and 8, and FX Collections 1 and 2. Spark 2 doesn't work.
• Camel Audio: Camel Phat, Camel Space, Alchemy (these are no longer available since Apple bought Camel and killed these plugins outside of Logic X)
• Cherry: CA2600, haven't tried others yet
• FL Studio (as DAW and as plugin)
• GForce: Imposcar2; Oddity 3, Minimonsta 2, Imposcar 3 all have issues.
• Korg M1, Wavestation, Triton and Triton Extreme, Polysix, Mono/Poly, MS20, work fine* Sonic Academy ANA2. Kick2 probably also works but I've hit my activation limit.
• Adam Szabo JP6K

Need dxvk

Use winetricks dxvk. The following don't update properly with the built-in dxgi.dll but do work with the dxvk one.

• Cableguys audio works but without dxvk the UI doesn't update
• GForce: Imposcar3, Minimonsta2, Oddity3, DMX

So far this works for a T470s with Intel graphics and Kubuntu 24.04. I have been less successful with 22.04 and nVidia.

What Doesn't

• Spire crashes
• Arturia Spark 2 crashes
• Korg ; ARP Odyssey and Prophecy (UI doesn't update with builtin dxgi.dll, and doesn't appear with dxvk)
• Superwave don't work
• Tone2 Icarus 1 (got via Computer Music) doesn't work.

GUI Updating Issues

This seems to be a common thing. They rely upon dxgi.dll. The dxvk version doesn't work, and the built-in one has the updating problem. I presume that, at some point, the Wine project will update dxgi.dll to one that does work for apps like this.
