@Claymoar for what its worth the ReaPack plugins have some solid functional replacements for L3/C6. I think the multi-band is ReaXComp. There is also the linux studio plugins (LSP) pack that includes a lot of functional LV2 and CLAP plugins that can do what you’re looking for. Depending on your distro it can be installed from your package manager directly.
I suspect the primary issue Waves has with unlocking the Linux compiled plugins they have for their servers is that they don’t want to build a new license manager - since they rely on Powershell for their Waves Central windows install and operation. Its like they WANT people to pirate the server versions to be able to use them on Linux - either that or they want us to just not use their product if we wont use windows. Until they show us solid evidence of giving a damn we have to assume its either of those things. They could even add a disclaimer/waiver that they dont offer full support for the plugin on linux similar to what SSL/Harrison does for their plugins - you know, one of their major competitors in the studio space. It would be spectacular if we could just use the plugins native, I’m sure we would all deal with some hiccups if we had access to them without ■■■■■■ workarounds.
