Felt & Fog for Kontakt 8 [Full version]

Felt & Fog is a six-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. €49, with a free demo if you want to try before you commit.

The six 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.

EP Ambient — a processed electric piano with a soft shimmer. The romantic layer. Sits beautifully behind dialogue without competing with it. 

Use it for: love scenes, tender flashbacks, slow indie ballads, Mac Quayle-style soft underscore.

The Fog — time-stretched particles that bloom into an ethereal haze. The layer that sounds least like a piano. Use it when you want atmosphere, not melody. 

Use it for: dream sequences, transitions, scenes with no dialogue, ambient-only cues.

Octave Swarm — a dynamic, octave-layered Swarm. The most active layer. It moves on its own and adds harmonic motion to a held chord without you touching anything. 

Use it for: evolving sustained pads, generative sketching, the moment in a cue where you need something to shift.

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.
