The signal path
PolyBLEP saw & square, a pure sine, plus a dedicated sub — detune them, or hard-sync osc 1 to osc 2 for the growl.
A Moog-style 4-pole, switchable 12 or 24 dB/oct, with resonance that climbs all the way to self-oscillation.
A VCA shaped by its own envelope — the final gain stage that lets each note breathe and decay.

Drop it in
Open the installer. Double-click Fish-Station.pkg and follow the prompts — it drops the VST3 and CLAP into /Library/Audio/Plug-Ins.
Rescan plug-ins in your DAW. In Ableton: Settings → Plug-Ins → Rescan. Live loads the VST3; any CLAP host takes the CLAP.
Add Fish Station to a track as an instrument, and play something low.
Requires macOS on Apple Silicon (arm64) — Intel Macs and Rosetta aren't supported.
