Abstract
A tone synthesizer for complex tone modeling, synthesis, or reproduction for simple to complex instruments, both real and imagined. The tone synthesizer has a wave generator that is responsive to a key signal from a key signal generator to produce an analog or digital wave. The key signal corresponds to a discrete musical note value. A preferred digital wave generator for a digital tone synthesizer is a DSP with componentry to read from a digital memory, generally a large RAM, one or more previously recorded, or sampled, digital waveforms loaded to the RAM. The digital wave generators selectably respond to a key signal to produce a primary note output in the from of a digital wave, or to a sympathetic note signal from a sympathetic note signal generator to produce a sympathetic digital wave. The sympathetic note signal generator is preferably responsive to at least one sympathetic note signal generator input to produce the sympathetic note signal, and can produce multiple sympathetic note signals to multiple digital wave generators. The digital wave generator producing the primary note output digital wave and the digital wave generator producing the sympathetic digital wave coopera…
