Low end,
sounded from
the deep.

Fish Station is an original monophonic subtractive bass synth for macOS — three oscillators into a Moog-style ladder filter, with two envelopes, an LFO and an arpeggiator. Written from scratch in Rust.

The panel

Every control on one face.

The Fish Station plugin panel — a dark brushed-metal face with brass-bezelled knobs, grouped into Oscillators, Filter, LFO, Arpeggiator, Amp and Filter envelopes, and Master, with a patch browser across the top.
No menu-diving — every parameter is on the front panel, and it resizes to 100 / 150 / 200 %.

The signal path

Everything a bass line runs through.

osc

Three oscillators

PolyBLEP saw & square, a pure sine, plus a dedicated sub — detune them, or hard-sync osc 1 to osc 2 for the growl.

flt

Ladder filter

A Moog-style 4-pole, switchable 12 or 24 dB/oct, with resonance that climbs all the way to self-oscillation.

amp

Amp & out

A VCA shaped by its own envelope — the final gain stage that lets each note breathe and decay.

↳ and tapping into that path —

Filter envelope ADSR into cutoff, blended with velocity and key-tracking. Amp envelope A second ADSR driving the VCA. LFO Free-running or tempo-synced → pitch, filter or amp. Arpeggiator Up, down or up-down, locked to host tempo.

Drop it in

From download to first note.

  1. 1

    Open the installer. Double-click Fish-Station.pkg and follow the prompts — it drops the VST3 and CLAP into /Library/Audio/Plug-Ins.

  2. 2

    Rescan plug-ins in your DAW. In Ableton: Settings → Plug-Ins → Rescan. Live loads the VST3; any CLAP host takes the CLAP.

  3. 3

    Add Fish Station to a track as an instrument, and play something low.
