Ephemera instrument

Pollen turns sound into a living granular field.

Scrub a source, widen the spray, freeze the read head, and let thousands of grains settle into pads, dust, rhythm, and noise-bloom.

How it works

1. Choose a source.Start from airy noise or brittle rustle textures.

2. Spray grains.Density, duration, jitter, filter spread, and pitch define the cloud.

3. Perform the field.LFOs, mod routes, FX, presets, and the studio strip keep the texture playable.

Grain cloud

A CPU carrier schedules precise grains with density normalization, pitch jitter, pan spread, envelopes, and filter motion.

The canvas mirrors the active grains as a rising pollen field, with the waveform showing source position, spray, and freeze.

An optional Layer-2 bridge adds a dense residual texture when SharedArrayBuffer and GPU support are available.

Pollen appears as a first-class Ephemera Studio instrument, with the same source-bridge path as the rest of the family.

FAQ

No. The core grain instrument runs without WebGPU. The swarm layer is additive and falls back cleanly.

The launch build starts with curated sources and the engine path already supports decoded audio buffers for future source import.
