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).
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."
