An electronic organ, several models of which have been manufactured by Norwich Organ Manufacturers at Lamas near Norwich since 1975. The two- and three-manual organs are designed for use in churches, schools, and homes (some are used at military posts and crematoria), and are based on the defunct Miller organ with extensive technological improvements; the names of the standard models (such as Sprowston, Norfolk, and Classic) were taken from the Miller range, but custom-designed specifications (e.g. North German) are offered. In 2010 the standard models were named Walsingham, Sandringham, and Sprowston. The original Miller system of a valve oscillator for each note was combined in the Norwich organ with one in which the sound is produced by 12 oscillators using frequency division. The firm later adopted solid-state electronics and digital reproduction aimed at producing pipe-like realism, for example in attack and decay characteristics. A special feature is the electronic simulation of the ‘chiff’ transient attack found in flute stops on some pipe organs....
