The technology

The Reactional Engine – created by research and collaboration by musicians, composers and software developers.

The Reactional Music technology was first invented by internationally acclaimed classical composer Jesper Nordin. His music is regularly performed by major conductors like Esa-Pekka Salonen and Kent Nagano, with world-leading orchestras including the San Francisco Symphony and the Philharmonia Orchestra.

After studies in computer music at Stanford University and Ircam/Centre Pompidou he invented the first version of the Reactional technology for his own compositional needs. Following continued research in interactive music—and collaboration with composers, coders and video game composers, all with university degrees in composition—Reactional’s patented technology is now ready for prime time.

Why it matters
