was film composer David Campell, Beck's father, who also arranged music for Tori Amos, Elton John, The Rolling Stones, Kiss, Aerosmith, and films, such as Brokeback Mountain. It was reportedly kept in friend Chick Corea's studio for several years before being acquired by musician and noted aficionado of vintage synthesizer gear Brian Kehew. Legal troubles and the ADS 200-R By 1981, Yamaha began to take notice of Con Brio's use of FM synthesis, on which they owned a patent (although the legality of the patent was in doubt, as FM synthesis had been used commonly for many years before Yamaha's claim). Because the ADS 200 used FM synthesis extensively, Yamaha warned Con Brio that royalties would be requested if any more ADS units were sold. Con Brio replied that because their device was completely configurable, they did not have control over whether or not the device was used as an FM synthesizer. Although Con Brio continued to violate Yamaha's patent, legal action was never taken, presumably because Con Brio was never successful enough to become a major competitor. Yamaha would later implement FM synthesis with their wildly successful DX7 synthesizer. In 1982, Con Brio introduced the ADS 200-R, a three-piece, detached double-keyboard model that was marketed toward touring musicians as being "roadable." It featured a 16-track polyphonic sequencer capable of storing 80,000 notes. At US$20,500 (about GBP£11,500), with an additional US$25,000 (about GBP£14,200) of options available, the 200-R was significantly less expensive than the original 200. However, the one unit that was built failed to sell. Although Con Brio considered retooling it into a sampling workstation similar to the Fairlight CMI, the cost of their operation and pressure from cheaper synthesizers and larger manufacturers forced the company to go out of business later that year before their vision was able to be realized. Aftermath In the years since Con Brio's demise, Danziger and Lieberman have become successful manufacturing semiconductors. Tim Ryan, motivated to continue manufacturing music equipment, cofounded The Sonus corporation, which later became M-Audio, a leading manufacturer of computer audio interfaces, MIDI controller keyboards, and studio monitor speakers. The one Con Brio ADS 200 that was ever sold now belongs to Brian Kehew of The Moog Cookbook. He claims that it was originally the ADS 100 and that it was retooled as the 200. In the years he has owned it, some functions have ceased to work, including the
