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.
