Not a piano and not a synthesiser, but the somewhere in-between

Beautifully worn and naturally warped, Lost Piano is designed to create a mood and inspire the way you play. Instant cinema. It’s not a synthesiser but neither is it really a piano anymore. It’s the somewhere in-between that you won’t have been before.

Created for experimentation. Created to push the limits on what you thought a piano could sound like. Made from 32 sets of piano sounds that have been time-stretched and transformed through reel-to-reel, cassette tapes, guitar pedals and some unconventional plugin chains.

It also features our new custom Memories engine which generates an intelligent pattern of rhythmic sounds. More character and complexity than an arpeggiator. More curious and unconventional than a delay.

This is for the composers, creators and music makers that value the way a sound makes you feel. It’s time to get lost . . .

“This latest creation from Westwood provides a welcomingly organic sound, whilst at the same time sounding excitingly unfamiliar. For all the wanderers out there Lost Piano might be just what you are looking for, with its dizzying combinations of heavily processed upright piano samples in a deep Kontakt engine.”

Listen to Lost Synth

Piano sounds

There are 24 different sets of piano sounds and 8 texture pads that can be loaded into 2 sides of the instrument. They have all been painstakingly re-recorded, re-amped and re-worked from the original Alt Piano recording sessions. They have been stretched and transformed through reel-to-reel, cassette tapes and some of the world’s finest boutique guitar pedals. Some have been further manipulated with a string of unconventional plugin chains.

We also went back to the original piano and recorded some additional interesting sounds using wooden plectrums, drum sticks and muted plucks.

Piano textures

The 8 texture pads have been made using similar re-recording techniques to the other sounds. The feeling of an analogue synth, but with the soul of a piano.

One of our favourites is called ‘Muddle’ which uses the highly revered, Fairfield Circuitry “Shallow Water” pedal and an Electro Harmonix Octave generator. We re-sampled both left and right channels independently, constantly changing the controls of the pedals to give a truly original stereo sound.

Rhythmical underscore

We’ve developed a custom engine called Memories which creates an intelligent pattern of notes to accompany your playing. More character and complexity than an arpeggiator. More curious and unconventional than a delay. Turn a simple chord into a rhythmical and moving soundscape of complimentary notes and tones.

Choose any of the piano recordings for the Memories engine to play and then refine the sound of them even more. Make them feel like a recent memory or a long forgotten and hazy dream. We’ve created 12 presets just for the Memory page, to give you an instant starting point.


We’ve included a switch that randomises almost every single sound and control in the whole instrument to take a dive into the unknown.

Maybe it will sound like that one time when you were 6 and recorded the family piano on your dad’s reel to reel. Maybe it will sound like the darkest memories of a stranger you’ve never met. Maybe it‘s a sound you never imagined was possible that’s just about to kick start your entire score.

Who knows where you’ll end up?

We’ve created 12 film-inspired reverb impulses. The room of a Japanese hotel. A ball room where all work and no play makes Jack a dull boy. An empty house being used to make soap. A spaceship where Dave is no longer in control. See if you can guess them all.

Film-inspired spaces











The built-in delay engine houses 5 different types of delay from a clean digital delay to several vintage and analogue inspired delays. Plus a delay we call Haze, where you can create a washed out shimmery cloud that blurs the line between delay and reverb.

Put it in a space

To add some instant atmosphere we’ve included 6 ambient recordings. From a calm breeze in woodland to a distant city at night. Recorded and edited to give a subtle undertone but without taking over.
If you think music shouldn’t sound pristine, there’s a series of 6 analogue recorded noises to take the edge off. Worn cassette tape, vinyl crackle, radio static and the drone of a forgotten machine are among the sounds available to make everything a bit more rough around the edges.

Take off the edge

Get started

With the endless range of possibilities in the instrument, we’ve created over 100 instrument snapshot presets to get you somewhere good quickly. Arranged in a way to find a simple starting point that you can take in your own direction, or choose one of the more complex and interesting combinations you might not have thought about.

Any questions?

I need a character upright piano, is this it?

If you’re looking for a traditional upright piano, this probably isn’t it. There are lots of very familiar piano-style sounds in the instrument, but they’ve been re-sampled and changed beyond the original recordings of a piano.

If you want a piano that feels like a real acoustic instrument with multiple mic positions, key, pedal and other piano noises then please look at ALT PIANO.

Will this work in the free version of Kontakt?

Yes. Lost Piano works using the free Kontakt Player, version 6.2.2 or higher.

Many of our other instruments do need the full version of Kontakt, so please ensure you have the correct version before purchasing anything from us.

Can I use this in commercial releases?

Yes! What you can’t do is repackage the individual samples or re-release them as another sample library, but you can absolutely use them to make the next score to a film about a linguist trying to communicate with an alien species.
