Congenital heart disease is the most common birth defect in the world. The CHD–4 is a drum machine created with such defects. It was developed in a collaboration between teenage engineering and audiovisual designer Love Hultén to raise awareness for the issue of CHD on behalf of the Swedish Heartchild Foundation. The device, functioning as a modular synthesizer, produces rhythms made using the echocardiograms of four children with different heart defects decoded into a sequencer, making it possible to play the heartbeat of each child.
On Valentine’s Day 2023, CHD-4 will be auctioned off with all proceeds donated to Hjärtebarnsfonden (Swedish Heartchild Foundation).
