Modulr Sieve

Three filters with personality, and a sixteen-step pattern that plays them for you.

Modulr Sieve is a filter with three characters: a comb, a formant (vowel) filter and a ladder. On top sits a sixteen-step pattern you draw with the mouse — the filter then plays that pattern in time with your song, the classic trick behind a generation of dance records. The picture always shows the filter as it really is.

Install it

Version 0.1.0, 2026-11-06.

The Modulr Hub app installs it for you, one click, and checks the download on the way in. Prefer doing it by hand? Unzip the file into the folder shown. Ad hoc (no Developer ID) and not notarised, so the first time you load it macOS asks you to allow it (System Settings, Privacy & Security) — normal for a small maker, and it only happens once.
