An upright piano with stories to tell

Alt Piano is an old, humble and character-filled upright piano from the 1960s. Recorded with and without felt, this piano has two very different personalities; soft and beautiful or bright and lively. The original recordings have also been transformed into a series of inspiring textural layers. These can be used to create a subtle background ambience to the piano, or made into their own atmospheric organic sounds. There are dozens of other unique controls, making this piano impressively versatile and allowing you to easily create an extensive range of sounds for any genre.

Natural or felted

(or somewhere in-between)

We recorded the piano twice. With and without felt which provides you with two very distinct characters. Both are full of subtle imperfections and individuality.

The natural sound of the piano without felt is bright and lively, whilst the felted recordings are soft and gentle.

But best of all, you don’t have to choose. We created a control which lets you blend between the two recordings to dial in a sound that suits you.


“If you need a piano that is an amazing ‘go-to’ for multi purpose then this is the one. I’ve found it’s possible to get everything from intimate to epic from it very quickly.”

Customer reviews

“Alt Piano is one of the most wonderful and inspiring upright piano keyboard libraries. Westwood is really something very special. ”


“That Transpitch feature should be in every piano library ever, it’s so useful and gives the recordings so much new life.”

VI Control

“Ah shucks, I have dozens of piano libraries but they’re either clean sounding or felted, so decided to go for this one. I love the sound but also all the options. And how is this so cheap??!!!!”

VI Control

“I legit own every felted piano sample library known to man lmao, but this absolutely takes the cake. The most fun I’ve ever had playing a sample piano library; the customisation and feel of the whole thing is just so impressive, especially for it’s price point. Thank you for taking such time and care sampling this, and creating a truly wonderful VST ya’ll rock.”



Subtle ambience or full blown vibe

The original session recordings have been transformed into 11 textural layers. Add a subtle ambience to augment the main piano or use them on their own in the front and centre of your music.

We used a combination of vintage cassette decks, time-stretched reel-to-reel, boutique guitar pedals and other experimental techniques to create a range of distinct sounds, full of character and soul.

To add even more interest, the sound of each one can be changed in its own unique way using the texture slider.

Behind the recording

We recorded the piano in the crypt of a church. It’s lived there for the past 10 years since a band we know have recorded all their albums in this unlikely place.

We used an absolutely world-class pristine signal path, capturing everything at 96kHz through legendary Neve 1073 pre-amps and Burr Brown AD convertors.

The signal started with a matched pair of Coles 4038’s as close as we dare put them to the hammers, to capture a really detailed sound. A stereo pair of AKG 414’s made an excellent job of providing a more natural and open perspective. We used a pair of SE-2’s on the rear soundboard which gives you a boxy and bright sound. Finally we set up another stereo pair of AKG 414’s right in the furthest and vaults of the room to record a really distant and ambient perspective.
