Product Info


Truly unique upright piano

Every single note has been tuned to E in their appropriate octave, making the single biggest E possible.

All notes sampled at once

Rather than sampling each key separately, every key was played simultaneously to create the ultimate E sound.

30 dynamic layers

Further customize the instrument with adjustable dynamic response and filtering.

2 distinct stereo mic positions

Exquisite detail for the full sonic range of this majestic instrument.

29 sound design snapshots

Textures, soundscapes, mega-hits and more… all “E” themed, of course!


Streamlined, modern UI

Spacious yet elegant style works great on 4K and Retina displays.

Super stacking options

Don’t stop at 88 notes! Voices can be stacked up to 3x with detuning and spread for more wideness.

Tone shaping controls

Adjust sample offset, tone, volume envelope, and velocity curve to completely transform the instrument.

Microtuning engine

Select from over a dozen preset tunings and temperaments, or create your own microtuned scale.

Console FX Rack and Mixer

Dozens of modules from analog-style EQs and compressors to convolution reverb, distortion and more.

Mattias Krantz has done it again: another truly unique piano modification experiment (with over 3 million views on YouTube and counting) where every key on the piano has been tuned to E. And what better way to play such a piano than to play every note at once?!

Welcome to The 88E, a free — yet surprisingly inspiring — virtual piano. Mattias has sampled this majestic instrument with 30 dynamic layers, providing a wide spectrum of tonal fullness. Naturally, the samples are also re-pitched in our Kontakt UI, allowing you to play whatever pitch you’d like.

To inspire your epic, cinematic, and soundtrack work, we’ve created several dozen snapshots that morph the core sound into everything from drippy plucks and resonances to dramatic, cosmic-level soundscapes. Besides these snapshots, you can adjust the instrument’s touch & feel to your personal preference with easy controls for tone, velocity response, filtering, and more.

What is the Engineer Series?

Mattias Krantz is a guitarist and YouTuber known for his wild, imaginative experiments with pianos and guitars. We are collaborating with him to bring his unique instruments to composers and musicians around the world. The series also includes Hammer Klavier, with more to come!

Console: Modular FX Rack and Mixer

Console is a fully-featured mixer, modular effects rack, and pedal board, designed to give you full control over your mix. Effects include multiple EQs (digital and analog-style), compressors, spatial FX, modulation FX, amps, distortion pedals, reverbs, and more.

Each mic channel can be loaded with up to 8 FX in any order, plus another 8 slots on the master channel, with support for send routing as well. The new “Galois Reverb” added in Kontakt 6 Player sounds fantastic as an alternative to our included custom IRs.

The 88E – DixonBeats

“…the 88E piano is so dark-sounding – very haunting sounding…although you can use this in, like, dark melody production, I can hear this predominantly being in movie scores, and things like that.”

The 88E – Simeon Amburgey

“This is a one-of-a-kind piano; nothing else on the planet like that…just huge…it’s got just such an unusual punch to it; it’s crazy…it’s just incredibly unique…and the effects just really take it to another level…thanks to Impact Soundworks and Mattias (Krantz) for coming together again to give us just another one-of-a-kind, fabulous experience.”
