description: "An open-source suite of Max/MSP externals emulating five studio equalizers and five compressors — optical, FET, and vari-mu types — usable directly in Max or as devices inside Ableton Live, with optional 8x oversampling."
---

Ten Max/MSP externals stand in for a full outboard rack: five equalizers running from a transparent air-band shelf to a tube-saturated passive design, and five compressors spanning optical, FET, and vari-mu circuits, each ported from open-source analog-modeling code and tunable with up to 8x oversampling. Drop them into Max or run them as devices inside Ableton Live — no plugin purchase, no license key.
