User interface Lost Piano Westwood

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.”

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.

Customer reviews

“More sublime and wonderful sounds and another amazing gui design from Westwood.”

VI Control

“Fantastic. This sounds gorgeous. Westwood nails it every time. Hats off!”

“This is really good stuff. Well done! Not only is it absolutely lovely, it looks like it is incredibly usable across so many projects.”

VI Control

“I own all your instruments, and I’ve found places for them in nearly everything I’ve written recently. They are truly inspiring. It’s a crowded field of “treated” piano VSTs, but you’ve brought the Westwood touch, and it’s beautiful. “


“Just got this. It’s amazing. The interface is so easy to use and the FX are brilliant. It’s like an all in one toolbox to get many different tones for very quick inspiration, instead of loading up other 3rd party FX.”

Rhythmical underscore

The MEMORIES engine creates an arpeggiated underscore. Load any of the sounds and transform them into a distant haze or a more upfront accompaniment. More interesting than a delay, more sophisticated than an arpeggiator.


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?


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.
