P2piano, a peer-to-peer platform for real-time collaborative music creation, is generating buzz on Hacker News. Users are excited about its potential for musicians to play together remotely. Initial comments express enthusiasm and describe the platform as a collaborative piano/synth/bass interface. However, some users initially encountered a blank page, likely due to the "HN HoD" (Hacker News Hug of Death). A commenter clarified its features, explaining that after creating or joining a room and setting a display name, a collaborative piano/synth/bass interface appears. The creator has also started a blog series detailing the development process for those interested in the technical aspects.
