Quick start
- Run the installer. It puts the VST3, the AU (macOS), and the standalone app where your host looks for them.
- Open GrindSub on an instrument track and play something around C1 to C2. You are hearing the Init patch: sub at -6 dB under a filtered, shaped saw.
- Turn Cutoff. Its readout is in semitones above the note you are playing, so “+24 st” means two octaves above the note, wherever the note is.
- Turn Resonance up. The readout beside it names the cutoff as an interval, and the filter’s peak lands on that interval, in tune, across the whole range.
- Step through the factory presets with the arrows in the header.
A fresh install runs as a trial: 14 days of use, everything working. After it ends the plugin still loads and still opens your projects; it stays silent until you register your license (see Registering, the trial, and updates).
