During the International Synth Design Hackathon 2023, we discovered a new planet. The planet of subtle stirring. We called it ‘Frederic-213’, as Frederic Chopin was a master of gentle blending of harmonies. We’re approaching his 213th birthday and we’d like to celebrate it by searching for harmonies of the universe. Subtle movements let us put Frederic-213 at the right point in space-time, exploring the wide range of smoothly changing chords. ‘Frederic 213’ apart from being a sound creation tool is also a game aimed at achieving a certain harmonic chord, different for each level.
