4Comp: AUv3 Compressor app analytics for October 9

4Comp re-skins itself to match the compressor you pick. Choose FET, VCA, Optical or Vari-Mu and the whole interface — face, knobs, meters — takes on that hardware's colours, so the plugin feels like the machine you're reaching for. FET Fast gain reduction from a feedback detector, with an all-buttons mode. Hi-hats, drum buses, spiky guitars. Ice-blue face. VCA Bus glue with program-dependent AUTO release. Tames transients and spikes without grabbing. Crimson face. Optical Smooth, level-dependent release from a modelled photocell — the cell's light memory. Vocals, brass, strings. Electroluminescent-green face. Vari-Mu A ratio that rises with level, plus harmonic colour that thickens thin tracks. Mix bus and mastering. Brass face. Four separate DSP paths Each model is its own compressor engine rather than a preset over one circuit: feedback FET, two-stage VCA, photocell release, rising-ratio tube. Switch faceplates mid-session and the plugin animates to the new model's look. Complement it Stereo link (Linked or Dual Mono), sidechain high-pass, dry/wet mix, input/output and auto make-up gain, a VU-style gain-reduction needle and 17 presets. Real-time-safe DSP, 0-sample latency by default.
