Yes. 1ON1 Piano works with the Steinway Spirio R, which can both send and receive piano-to-piano data. It also works on some Steinway Spirios (Steinway Spirios have playback-only functionality and some do not have a port to connect to piano-to-piano). If you have questions about whether your Spirio will work for piano-to-piano, contact our 1ON1 Piano support team and we will help you sort it out.
