摘要： A resonance strength table is prepared, which stores a relation between a pitch difference and a resonance strength, wherein the pitch difference is a difference between a pitch assigned to the key number of a pressed key and a pitch assigned to each of key numbers of a resonance tone. When a key is pressed, the resonance strength table is referred to, and resonance strengths concerning the key numbers of a resonance tone are determined. Then, note-on events of a resonance tone are produced based on the key numbers and the decided resonance strengths and the produced note-on events are sent to a sound source.

摘要： A string signal generator generates a string signal representing vibration of a string corresponding to a specified pitch in response to a note-on instruction such that the string signal rises and then attenuates in response to a note-off instruction. The string signal generator distributes the generated string signal to a plurality of loop circuits of a string resonance simulator. The plurality of the loop circuits correspond to a plurality of pitches and circulate resonant signals of the corresponding pitches, each loop circuit having a delay element for delaying the resonant signal by a time depending on the corresponding pitch, and an attenuation element for variably attenuating the resonant signal according to an attenuation coefficient. A controller respectively provides attenuation coefficients to the attenuation elements in the plurality of the loop circuits based on the note-on instruction, the note-off instruction, a damper-pedal-on instruction, and a damper-pedal-off instruction.

摘要： A music sound generator imitates released key string vibration sounds (RKSV) and cabinet resonances of an acoustic piano. When a key is pressed, waveform is readout from a normal music sound waveform memory 15. The normal sound waveform is inputted into a filter 21, and inputted into a filter 22 through a band-pass filter 33. Output waveform of a cabinet resonance waveform memory 17 is inputted into a filter 23 when the key is pressed. Outputs of the filters are synthesized by an adder 27 through multipliers 24 through 26. When the key is pressed, a cut-off frequency of the filter 22 is sufficiently low and RKSV is not generated. If the damper is not on when key-releasing, the cut-off frequency is returned to normal and RKSV is generated. A level controller 32 attenuates the RKSV and the cabinet resonance for a longer time than the normal music sound.

摘要： Resonators generate resonance sound data of given resonant frequencies based on sound signal data corresponding to a pitch of a key. Each resonator includes a delay circuit which delays an input based on delay time data, a second adder which adds an output from the delay circuit to input sound signal data, and a low-pass filter which performs filtering depending on a filter control signal on the output from the second adder. An output from the low-pass filter is input to the delay circuit, and a first adder adds outputs from the resonators. A storage device stores a coefficient table containing items of delay time data to be provided to the resonators, and the items of the delay time data do not match with frequencies corresponding to pitches of keys.

摘要： 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 cooperate to produce a summed digital wave output which is the digital sum of the primary digital wave and one or more of the sympathetic digital waves. Also a digital tone synthesizer has stored digitally sampled note data, the note data having been sampled at a sampling frequency F, with a sample period of 1/F, and has a DSP clock operating at a DSP clock frequency; a slot count incrementer for incrementing in a slot counter a slot count of a selectable number of slots n, each slot having a slot duration defined by a selectable number of DSP clock ticks T. It also has a system clock producing system clock ticks and operating at a system clock frequency equal to a whole number multiple P of the sampling frequency. It also has a reset counter for counting P system clock ticks and thereupon effecting a reset signal to the slot counter.
