Petri

Ten living cultures. One plugin. Every sound grows in a dish, and every knob changes what grows.

Instrument and effect. VST3 and AU for macOS, Windows to follow. Opening 2027.

The cultures

Ten Petris. None of them stock.

Each dish grows its sound from a process found in a lab: reaction diffusion, cellular automata, predator and prey, an epidemic, quorum sensing. Two knobs for the organism, two for its medium.

  • Moss, grown in the plugin
    MOSS 01MOSSHarmonics that grow in clusters. Warm dust, soft grit.
  • Spore, grown in the plugin
    SPR 02SPOREA waveform made of living cells. Digital rot.
  • Indigo, grown in the plugin
    IND 03INDIGORatios that drift like ink. Glass, then struck metal.
  • Bloom, grown in the plugin
    BLM 04BLOOMPredator and prey fold the bass. It never repeats.
  • Petal, grown in the plugin
    PTL 05PETALA frozen spectrum that smears and wilts. Pure air.
  • Physarum, grown in the plugin
    PHY 06PHYSARUMFive oscillators lock and let go. A reese that breathes.
  • Phage, grown in the plugin
    PHG 07PHAGEAn outbreak moves a mouth. Every note talks.
  • Mycelium, grown in the plugin
    MYC 08MYCELIUMStrings that branch and fork. Wood, wire, drone.
  • Diatom, grown in the plugin
    DTM 09DIATOMStruck glass, plates and skins. Kicks included.
  • Lux, grown in the plugin
    LUX 10LUXA tone that lights up when enough gathers. Chaos on cue.
How it works

One plain chain.

Read it like the panel, top to bottom. No modes, no routing. In Petri FX your own sound takes the organism's place.

  1. 01

    Organism

    The sound source. Grows a tone from its own maths.

  2. 02

    Medium

    Two effects that colour it, one meaner than the other.

  3. 03

    Filtration

    The filter. Five membranes.

  4. 04

    Percussion

    The punch, in time with the song.

  5. 05

    Perfusion

    The volume, pumped like a heart.

  6. 06

    Yield

    Out. Held under the ceiling, never clipping.

Filtration

A membrane with a cut off.

Five filters, solved without delay in their feedback, so a shaker can throw the cutoff around without a click. Drawn here from the plugin's own maths, at 1 kHz and 60 % Resonance.
