Mastino 60 is a direct compressor: threshold sets where the clamp begins, Compress sets how hard the detector turns gain down, and Output brings the level back where it belongs. It is built for decisive dynamics work rather than invisible levelling.
The sidechain filter changes what the detector listens to. Push it when kick drums or bass fundamentals are making the compressor overreact; pull it back when you want the full signal to drive gain reduction. Stereo Link controls whether the detector behaves as one linked stereo control path or lets each side move more independently.
Mix is built in because this style of compression often sounds best when the obvious version is blended under the clean one. Quality modes let you pick the right CPU/accuracy point for tracking, mixing, or rendering, while the plugin reports fixed low latency to the host.
Mastino 60 is offline-first. The plugin does not phone home during use, does not collect telemetry, and does not require an internet connection after activation. One license file, one plugin.
