I heard that audio assault is working on a new program. No info on their website. And because I don’t have any facebook or anything like that, I contacted them directly. The answer is ReAmp.
I bought it now and I can only recommend it to the guitarists
The Linux version will be in the final release.
They assured me that every program or VST they create from now on will have a linux version.
I tried the windows version and I’m excited.
