Format Fix
Use when audio files have the wrong/confusing format or won't load — 'this wav won't open in ffmpeg', 'convert these AIFFs to wav', 'resample to 48k', 'fix the 24-bit AIFF with a .wav name', 'Invalid PCM packet error'. Fixes the AIFF-as-.wav trap and does format/rate/bit-depth conversion with the right tools. Local shell, no MCP servers.
Vst Master
Use when the user wants to master a mix with their own plugins instead of the pure-DSP chain — 'master this with FabFilter/Ozone', 'plugin mastering chain', 'master using my Pro-L limiter', 'EQ+comp+limit this with my plugins'. Builds a measured plugin mastering chain (EQ → comp/MB → limiter) and verifies streaming compliance. The opt-in VST sibling of master-track. Stemmy MCP, the vst extra (streaming compliance is pure DSP — no key; GEMINIAPIKEY only for the optional perceptual read).
Vst Preset
Use when the user wants to save a VST chain for reuse or apply a saved one — 'save this chain as a preset', 'apply the vintage-1960s preset to this mix', 'reuse that drum sound on another track', 'make a preset from these plugins', 'list my vst presets'. Save & apply reusable VST chains (input gain-stage + enum/bool params + M/S narrow + state blobs) via presets/vst/.
