Felt & Fog [Demo version] is a three-layer ambient piano library for Kontakt 8. It's built for slow music, film cues, documentary underscore, neo-classical sketches, ambient and meditative tracks, atmospheric sound design.
The samples were hand-played without a click track, so every layer drifts at its own natural pace. Two of the six layers are Swarms, evolving clouds that don't lock to a grid. Hold a chord and it keeps moving. Nothing repeats in any way you can hear.
Made by Renger Koning, Amsterdam-based composer for film, documentary and contemporary dance. €0 if you want to try before you commit.
Demo version: three layers, and when to reach for each
Felted Piano — a warm, intimate upright with felted hammers. Reach for this when you need a pure, recognisable piano voice at the front of a cue. It's the only layer that doesn't loop, so each note fades into silence.
Use it for: sparse film themes, lo-fi piano, late-night documentary intros.
Minimal Swarm — subtle repeating notes that create a floating texture. The Eno layer. Pulse-like, but never on a grid.
Use it for: meditation tracks, slow-build cinematic openings, anywhere you want forward motion without rhythm.
Glass — harmonic overtones and resonances built with the Ferrous from Landscape. Adds depth and a slight unease.
Use it for: slightly eerie underscore, mysterious documentary cues, atmospheric sound design.
Every layer has its own mute, volume, pitch, delay, reverb and ADSR. Click any layer and its controls light up — no menus, no subpages.
