On 8 August 1967, Pasadena, CA-based North American Rockwell (hereafter Rockwell) and their engineer Deutsch filed a patent application for the digital organ. Soon after, Deutsch demonstrated this invention to the large U.S.
Nevertheless, in June 1971 Rockwell delivered the digital organ prototype to Allen and its technical attributes proved immediately apparent.
At the North American Music Merchants (NAMM) trade convention in June 1971, Deutsch arranged a private demonstration of Allen's digital organ to Yamaha's president and an entourage of 25 delegates.
During the Yamaha contract, Kawai approached Deutsch to undertake a similar function with regard to that firm's digital organ program.
Or, as the author of one of the most fundamental technologies in the field, could he separate his own tacit knowledge that formed the basis for the digital organ patent from the codified knowledge inscribed in that patent?
Many of these documents referenced either the digital organ patent or its cousin the 'computor' organ.
(7) Much of Kimball's claims of invalidity rested on the fact that Deutsch and Rockwell had 'demonstrated' its digital organ technology to Rodgers and Conn (two other U.S.
