While many earlier player piano systems rely on midi data files (compressed, low-resolution data files) and others rely on even lower resolution files for playback, Steinway & Sons is recording at the highest resolution possible, and has created a proprietary data file format that captures the nuances and full range of emotion from each artist’s performance.
This superior level of playback is made possible through a combination of proprietary high-resolution recording technology, and the Steinway Spirio’s ability to replicate smaller increments of velocity on both the hammers and proportional pedaling. The fact that the recordings are recorded and played on a Steinway & Sons piano exponentially increases the differences in performance quality when compared to existing products.
