IKKKO was a social music machine, founded and developed together with Stephan Schulz. Our web-based experiment was to become the karaoke platform for instruments, able to transcribe and share the underlying chords and notes for songs in YouTube videos. Our Flash-based editor had real-time synthesis in the browser. It allowed for the production of multi-track songs, and also for users to share these songs with one another. This project was made in 2010. Because contemporary browsers no longer support Flash, we took the project offline.
