Four analog-style compressors in one AUv3 plugin: FET, VCA, Optical and Vari-Mu. Each is its own DSP engine with its own sound, and the whole interface — face, knobs, meters — changes to match the one you pick. New in 1.1: tap ? for a quick start and a guide to each model, and watch the live transfer curve on VCA. 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. Brushed-steel face, ivory meter. 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 gain-reduction meter styled for each model and 17 presets. Real-time-safe DSP, 0-sample latency by default. Works in GarageBand, AUM, Cubasis, Loopy Pro and other AUv3 hosts on iPhone and iPad.
