Abstract
An electronic bell-tone generating system selectively provides a plurality of bell tones having improved tonal quality includes a plurality of tone generators operated in preselected combinations by a microprocessor in response to inputs from a keyboard. Data representing characteristic bells, including a fundamental tone and associated partial tones, their initial amplitude, and decay rate, is stored within a random access memory, input periodically to the respective tone generators comprising double-buffered, digital-to-analog converters, and output simultaneously to produce the 'strike' of a bell.
