Arturia Comp TUBE-STA is a warm, musical tube compressor recreation inspired by the legendary Gates STA-Level, beloved for its rich harmonic character and smooth, program-dependent compression. Three tube mode options — single, double, and triple — let you dial in the exact amount of harmonic coloring, from subtle warmth to lush saturation. The advanced sidechain with Mid/Side processing and filtering gives you precise control over the compression behavior, while the Mix knob enables effortless parallel compression. An essential mastering and bus processing tool for adding vintage analog character.
