Steinway has been making the finest pianos in the world for over 160 years. IPS was engaged in a technical deep-dive to thoroughly understand and quantify the complex, traditional mechanism. The team worked with Steinway to architect a system delivering ground breaking new features without sacrificing the instrument's exclusive tonal range and color.

With the detailed results of the audit, Steinway leveraged their in-house system architecture and mechanical engineering expertise to lay the foundations for the next generation of Spirio. Joined by a complementary team of IPS engineers, they set out to bring their design to life.

Automated Testing



To Steinway’s extensive and robust musical technology and intellectual property, IPS hardware and software engineers added a high-performance embedded control system, consisting of distributed microcontrollers networked for the high speed movement of data. The sensors and control system have been incorporated into the instrument without impacting the playability or sonic characteristics.

In order to authentically reproduce the nuances of the original performance, controllers provide precise timing in a multi-step note drive process, delivering accurate timing and dynamics of note events. Hammer velocity and proportional pedaling are all monitored hundreds of times per second. The high-resolution recording hardware captures the artist's performance ensuring accurate reproduction of dynamics, timing, and pedal motions.

But apart from the science of development, the true magic of Spirio results from its full integration with the actual music production within Steinway’s recording studios and post production facilities where thousands of hours recording hundreds of world class artists provide the meticulous detailed and nuanced performance testing required to build the finely tuned algorithms embedded in Spirio.
"Spirio | r technology integrates seamlessly ensuring no alteration in the musical performance nor compromise in the instrument's beauty."
Hammer Behavior Testing
To offset the inherent variabilities present in a hand crafted centuries-old mechanical design, we engineered multiple self-calibration processes that allow the control system to adjust its note drive waveforms and maintain consistent sound quality and accuracy.
"The soft trills, delicate pedaling, and thundering fortissimos that separate the world's finest artists are reproduced with unparalleled accuracy by Spirio, precisely realizing both the pianist's and the piano's entire range of motion and emotion."

"Spirio enables you to enjoy performances captures by great pianists - played with such nuance, power and passion that they are utterly indistinguishable from a live performance."


A Cross Functional Symphony

In collaboration with Steinway & Sons, IPS' engineering and design teams have worked in parallel to bring Spirio | r to market. Over a period of several years, IPS teams played a critical role in the implementation of the design, architecture, and underlying Spirio technology. Today, the IPS team remains engaged, improving the Spirio | r product family, deploying new features, and assuring quality through continual testing.
