Summary

Nicholas Joseph Porcaro (Nick) received a Bachelor's Degree in Electrical Engineering from Texas A&M University. After graduating, he spent 7 years working for Tegas/Calma and Aida/Teradyne, startup companies in the electronic design automation industry, where he participated in the development of software for schematic editors, logic simulators, and design language translators. Following that, he spent 2 years at a Stanford-incubated geophysical software startup with Pierre Samec, called PetroVision, developing signal processing software related to seismic data analysis.

In 1990, he became a visiting scholar at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University, at the invitation of Julius Smith, where he studied digital signal processing as applied to physical modeling of musical instruments. During this time, he started experimenting with object oriented programming on the NeXT computer, and developed SynthBuilder, which was supported by the Sondius project.

From 1996 to 2000 Nick was a founder of Staccato Systems, (which became a subsidiary of Analog Devices) where he continued to develop SynthBuilder for use as an internal tool for developing sound effects algorithms for games. In June 1997 SynthBuilder won the grand prize "Golden Max" award at the second annual International Bourges Music Software Competition.

After Staccato Systems was purchased by Analog Devices, he studied jazz piano under Dick Hindman, and played regular gigs in San Francisco. He also served on the board of directors of the Haight-Ashbury Neighborhood Council and continued software development by creating a prototype for an extensible online dictionary, along the lines of Wikipedia, called the Open Dictionary.

In 2002 moved to New York City to concentrate more on piano. He studied jazz piano under Eric Lewis, Connie Crothers and Latin jazz at Harbor Conservatory for the Performing Arts under Pablo Mayor. In 2005 he started playing a regular jazz gigs with many musicians, including percussionist and composer Lukas Ligeti. Nick was also a visiting composer at the Computer Music Center at Columbia University by invitation of Brad Garton during this time.

Starting in 2005 Nick began a painting/free improvisation collaboration with artist Ellen Levy, where abstract movies were created using Adobe After Effects and Max/MSP. This led to the development of a live 3D graphics/sound system using Pure Data and Blender called "Blendnik". As a result of this work he started the New York City Blender User's group which organized a conference at NYU Polytechnic University.

Since 2010 Nick has been spending most of his time working on two significant, iOS apps, both of which are in the iTunes store, "UndAground—New York" and moForte Guitar
