Spectrus

I'm giving this 4 out of 5.
The FX possibilities are very strong. With 24 effects available and flexible dry/wet mixing options, there's a lot of creative potential to explore. I'm holding back one star as there are still a few areas that could benefit from some additional polish, such as minor window resizing quirks and certain aspects of FX usability and overall user experience.

That said, I believe Spectrus is absolutely worth every cent and is on a very promising path. The combination of reverbs, echo, and delay is outstanding and can easily stand alongside other high-quality reverb plugins. The textures created with the stutter and granular effects are especially unique.

I really appreciate this tool and am glad to see such a great addition to the Linux community. I'm using Spectrus on a Debian-based system.
