In 2014, Williams Forrest began a multi-year partnership with Steinway & Sons. The impetus was the introduction of Spirio, a highly-advanced reimagining of the player piano. The proprietary software used to capture performances by some of the world’s best artists allows their emotionally-charged renditions to be experienced in living rooms, and not just concert halls. Williams Forrest was engaged to design, develop, and maintain the app used to control this exceptional piano.

Steinway & Sons Spirio represents the ultimate marriage of technology and luxury branding, a space that Williams Forrest operates in regularly. The end result is an app that, when displayed on the iPad above the piano, looks like it belongs there. This is not your average remote.
