Standing over 2 metres tall and weighing in excess of 70 kilos, Harpa Laser’s iron body dominates its surroundings with a strong sense of grandeur and power. The creation of such a behemoth required a suitably large effort. More than 100 hours of precision engineering was required to build the structure, in addition to the months of development of Imaginando’s award winning software synthesiser DRC, which Harpa Laser uses.

Harpa Laser has been featured at several public events such as Noite Branca Braga and TEDx and has been used to promote brands including Galp Energia and BMW.

Whatever the environment, the piercing green light ensures the focus of the crowd while the sonic siren of the synthesizer seduces the audience, inspiring and encouraging interaction.

Herein lies the true power of this instrument; an unforgettable, interactive, audio-visual experience which leaves a long-lasting impression.

Harpa Laser is the result of a shared passion for music, art and technology between Nuno Santos and Rui Antunes.

For the last 15 years the two have grown together whilst each excelling at their chosen discipline. Nuno became the founder of Imaginando, and Rui the founder of Analog Repair, a workshop in Lisbon dedicated to analog synthesizers repair.

After years of experience, the two joined forces to build an original synthesizer engine from scratch, merging the software development and system engineering skills of Nuno, and the deep knowledge of analog electronics and synthesizer architecture from Rui.

After a year building the synthesis engine, they found the perfect method to showcase it to the world: Inspired by the visionaire Jean Michel Jarre’s laser harp, they decided to build their own custom version.


Harpa Laser can be remote controller by DRC allowing it sound to anything that can be synthesized with DRC sound engine. Each laser beam was programmed to play a note from a minor scale where the outer and longer laser beam would play a lower pitch.

A random offset to the notes could be easily made by simply interacting with the last and shorter beam, providing variation while playing.
