Developer Renger Koning has released Felt & Fog cinematic piano for Kontakt, along with a free version.
They all offer something a little different, so there’s always room for one more (or more).
This time, we’ve got Renger Koning’s Felt & Fog library for Kontakt.
Felt & Fog isn’t a brand-new library; it’s been available on Decent Sampler for a while.
But, given the success of the Decent Sampler version and exceptionally positive feedback, the developer decided it’s time to release Felt & Fog for Kontakt.
The Decent Sampler versions (paid and free) are still available.
Like the original release, there are two versions for Kontakt: paid (€49) and free.
The paid version has six layers: Felted Piano, EP Ambient, The Fog, Octave Swarm, Minimal Swarm, and Glass.
The free version has just three layers: Felted Piano, Minimal Swarm, and Glass.
The free version is labelled as a demo because it has some limitations and doesn’t allow access to the preset library. However, it’s still a very usable instrument, and that’s what I’m focusing on today.
The basic felt piano layer is very nice, but it’s the addition of the other two layers that makes the library special.
Minimal Swarm adds an evolving texture with subtle repeated notes, and, while it’s subtle, it’s extremely effective. This layer even works on its own as a sparse atmospheric texture before introducing any real harmony.
The impact of the texture changes, depending on how you play the instrument, and that’s what I like most; it can add tension, anticipation, grit, and it moulds well to your harmonic choices, whether dark or light.
The Glass layer, slightly detuned harmonic overtones and resonances, is absolutely lovely in any application. It’s fantastic by itself as an ethereal or eerie textural pad with depth because, again, it really leans into the light and shade of your chord choices. It’s even better with Minimal Swarm, and it’s best with all three layers together.
Each layer has dedicated controls, so you can customise your blend to a decent extent.
You then have a bunch of master effects, including Flanger, Rotator, Distortion, Tape, Delay, and Reverb. The paid version has additional Formant and LPF effects.
If you’ve used the Decent Sampler version, you’ll see that this release features a significantly different, modernised interface.
I love a cinematic piano, so it’s no surprise that I’m really enjoying Felt & Fog, but it ticks every box; the core piano sound is good, it’s highly emotive, it brings texture, depth, movement, and blends everything very well.
Some instruments are perfect when starting with a blank canvas because the sound makes you think more about emotion and intent rather than progressions and theory; Felt & Fog is one of those instruments.
As a note on the paid version, the extra layers make a difference, and the obvious conclusion is that it’s better than the freebie. However, if you’re not in the market to buy, the free version offers more than enough for professional projects.
