Kaduk develops instruments and systems by placing the pianist at the centre — physically, artistically, and practically. We work from the belief that musical expression emerges through dialogue: between musician and instrument, between body and sound, and between artist and audience. By combining artistic intent with scientific and medical understanding, we aim to create a healthier, more direct position for the pianist, where control, expression, and long-term practice are supported rather than constrained.

Precision Instruments. Engineered in the Lab, Perfected on the Stage.

We are a research laboratory that builds the world's most advanced musical hardware. Explore our ready-to-use products or partner with us for bespoke development.

Our 4 pillars:

Instruments

Kaduk builds instruments that deliver the musical authority of historical concert grands without dependence on permanent venues or specialised infrastructure.

The result is consistent, transportable performance designed for sustained singing tone and precise musical dialogue, improving artistic freedom, economic independence, and long-term physical health for musicians.

We build instruments for what musicians actually need.

Piano Interfaces

Keyboard and action systems that define how a piano responds.

Kaduk designs complete keyboard and keyboard-action interfaces for professional use, developed as coherent systems rather than interchangeable parts. These interfaces are applied in restoration, modification, and selected new builds, with a focus on precision, repeatability, and long-term musical control.

Conservation

Kaduk is committed to preserving historically important instruments whose craftsmanship, materials, and musical qualities define a high point in piano making. Our work focuses on maintaining authenticity and playability, ensuring these instruments can continue to be used, studied, and experienced as intended.

R & D

Kaduk is fundamentally an R&D-driven studio. We continuously develop new musical interfaces, instrument architectures, and physical systems for our own work—often years before they become products. When relevant, we extend this research in close collaboration with selected partners, or apply it to external challenges where no adequate solution yet exists.

Timeline of Innovation

Monocoque Key Construction

The perfect key that gives unparalleled direct response

No matter the angle, no matter the conditions, our monocoque keys play always faster and more direct than wood could do.. Even if we use keys in very extreme angles.

2013

Hybrid Ergonomic Keyboard

A smaller keyboard in a grand piano with a silent system

The first ergonomic keyboard ever delivered on the market that is intended for an acoustic instrument, but that has a digital silent function.

2023

Automatic Custom Keyboard Creation

Any keyboard directly

Our advanced software package "keydesign" is the ultimate tool for designing piano keybaords of any sort in any build. It automatically designs and analizes constructions and simulates its real world behavior with exceptional presicion. The whole process of creating a perfect keyboard with predictable outcome within seconds instead of years.

Active Soundboard Technology

Actively and precisely controlled waves of vibration in our ultra thin soundboard

In every soundboard rich moving waves occur. The way they move is essential for the quality of the tone. Normally those waves are induced from an oscilator (the strings) and they develop in the board. In our system we directly control them in the board, giving us possibilities that mechanically are simply impossible. Also, contributing to our dedication to portability, the soundboard of our 4 meters long concert grand does not weigh thousands of kilos like one would expect, but 4 kilograms.

2024

Smooth Control Action

A refined acoustic grand piano action focused on control and consistency

Traditional grand piano actions suffer from variability, wear, and loss of predictability over time. The Smooth Control Action is developed to provide a lighter, more direct, and more controllable touch, with improved durability and stability under intensive use. Designed for use with Kipi interfaces, it allows more precise control over tone and articulation while maintaining consistent playing characteristics.

2025

Our journey has been marked by a series of pioneering advancements in piano technology. We've consistently led the way, delivering remarkable new innovations to our clients. Explore the milestones that define our commitment to pushing the boundaries of what's possible in the world of piano craftsmanship.
