Roberto del Rosario: One-man band Inventor
Music is an artistic form of auditory communication incorporating instrumental or vocal tones in a structured and continuous manner, and one true blodied Filipino have it’s own share of this kind of fashion. He is the inventor of the one-man band.

Roberto del Rosario has patented more than twenty inventions making him one of the most prolific Filipino inventor. Besides his famous Karaoke Sing Along System Roberto del Rosario has also invented:

Roberto del Rosario – Karaoke Sing Along System:
Karaoke is a Japanese expression for singing along to a famous record with the vocals removed. Roberto del Rosario described his sing-along system as a handy multi-purpose compact machine which incorporates an amplifier speaker, one or two tape mechanisms, optional tuner or radio and microphone mixer with features to enhance one’s voice, such as the echo or reverb to stimulate an opera hall or a studio sound, with the whole system enclosed in one cabinet casing.
Del Rosario, 71, died peacefully in August 2003.
We’ve lost an iconic Filipino inventor his colleagues assembled to again hear the story of the inventor who shuffled his way into Filipino hearts in 1972, when he gifted the world with his One-Man Band (OBM), an acoustic piano which plays in concert on its keyboard a full orchestra accompaniment of wind, string, and brass instruments to the different dance beats of cha-cha, boogie, disco, swing, and tango.
In 1974, he swept the world off its feet by his Sing Along System (SAS) invention (subsequently made better known by its Japanese pirates as karaoke). The SAS is a portable audio device consisting of a microphone and an amplifier combining a multitude of musical sound effects, which enhance the voice of the singer when played in accompaniment. It was originally designed as a teaching device for students taking voice lessons at del Rosario’s Trebel School of Music.
The SAS infringement case is the leading patent infringement case in the Philippines. While del Rosario’s Philippine patent was not enforceable in other countries where it was lavishly copied, he brought local infringers to court. Following grueling legal battles, the Supreme Court ruled in his favor with finality on January 3, 1998. His victory was hailed worldwide, particularly by inventors as the triumph of intellectual property protection and a warning to intellectual thieves.
Tenacious at his creative upbeat, he invented �voice color tapes� that grouped multiplex and minus-one tapes into three �voice colors�: blue, orange, and green, determined in turn by del Rosario’s patented method of determining a singer’s voice range.
Del Rosario, distressed that the Philippines was not giving much attention to its inventors, led the impassioned lobby at Congress for the passage of R.A. 7459 otherwise known as the Inventor and Inventions Incentives Act of 1992.
He was elected to the executive board of the International Federation of the Inventors Association – the first Filipino ever to attain such a high post. Of the many international and local honors conferred him as an inventor, he was most proud of the WIPO Gold Medal for Best Inventor awarded him in 1985.
Truly an iconic Filipino Achiever.
