摘要： An electronic keyboard instrument has a plurality of key displacement sensors disposed in relation to respective keys of a keyboard. Each sensor detects a continuously variable key displacement induced by the key operation to provide an analog signal indicative of the displacement. An analog-to-digital converter digitizes the analog signal at a predetermined sampling rate to derive a stream of digital samples of key displacement. A control, which operates based on a predetermined tone control algorithm receives and analyzes the stream of digital samples. According to the analysis, tone parameters such as envelope and vibrato are produced for controlling the characteristics of a tone, so that a tone having a very dynamic key touch response is developed. In a preferred embodiment, there are provided a plurality of tone control algorithms adapted to process the stream of key displacement samples in manners different from one another. A manually operative selector selects the desired one of the algorithms to be used by the control during the play of the instrument. "

摘要： An electronic drum has two or more batons, each baton having a transmitter which transmits a distinct radio frequency signal at a position in space. The electronic drum determines the current X, Y, and Z coordinates of each baton transmitter. To determine the position of each baton transmitter, the drum includes a tablet which has a flat support member at a predefined position, with at least two pairs of electrodes coupled to the flat support member. A first pair of the electrodes is shaped so that the amount of capacitive coupling between each baton transmitter and one of the first pair of electrodes corresponds to the position of the baton transmitter with respect to the X axis. A second pair of electrodes is shaped so that the amount of capacitive coupling between each baton transmitter and one of the second pair of electrodes corresponds to the position of the baton transmitter with respect to the Y axis. The electrodes pairs are shaped and positioned so that neither electrode pair shields the other, which allows for accurate X and Y position measurements. The drum also has a CPU which receives signals from the electrodes, and uses those signals to compute the X, Y and Z coordinates of each baton. The CPU also predicts when each baton transmitter will hit the drum's flat support member and generates a signal at the predicted time so that a music synthesizer can generate a sound at the appropriate time.

摘要： A touch response device for an electronic musical instrument includes pressure detector for detecting initial-touch and after-touch of a key. The pressure detector means has two or more response stages that have different response characteristics to key pressure variation. An initial-touch-detector signal is produced when the pressure detecting means is in a first response stage among the response stages, and after-touch-detector signal is produced when the pressure detecting means is in a second response stage among the response stages. According to the invention, initial-touch signal and after-touch signal are generated by the use of one common operation-detector signal produced from the pressure detector means. As a result, the construction of the pressure detecting means is much simplified compared with a conventional touch-response device provided with two separate detectors, one of which detects initial-touch and another of which detects after-touch.

摘要： An electronic musical instrument capable of effecting vibratos with any of tones which may be produced by pressing down the keys of a keyboard. A key constant memory stores key constants each being assigned to a different tone, while a vibrato constant memory stores vibrato constants each being assigned to a different tone. The keyboard is provided with an exclusive switch for effecting vibratos. When this exclusive switch is pressed, a counter which counts clock pulses feeds its output to an adder/subtractor in the form of an addition/subtraction switchover signal and an addition/subtraction execution control signal. In response, the adder/subtractor periodically and alternately performs addition and subtraction with the key constant and vibrato constant associated with a key being pressed down.

摘要： A musical tone signal generating apparatus generates a musical tone signal whose tone color can be changed independently of a pitch or a frequency of the musical tone signal. The musical tone signal generating apparatus comprises a shift register on which sampled data of a predetermined waveform are initially loaded. The sampled data in the shift register are shifted at a frequency corresponding to a rate of change of the tone color, and each sampled data shifted out of the shift register is subjected to a predetermined operation such as a multiplication by a predetermined coefficient and is fed back to the shift register. The sampled data in the stages of the shift register are selectively outputted by a selector controlled in accordance with selection control data formed based on the pitch of the musical tone so that the sampled data are outputted at a rate determined by the tone pitch. The musical tone signal is then formed based on the thus outputted sampled data. The shift register may be replaced by a random access memory, in which case the sampled data are sequentially read at a repetition rate determined by the pitch of the musical tone signal and the sampled data in the random access memory are modified at an interval determined by the rate of change of the tone color.

摘要： In the production of a desired musical waveform by combining harmonic components corresponding to respective harmonic orders, the cut-off harmonic order q.sub.c, each harmonic component value is controlled by selecting the level Ha and the slope of the Formant filter characteristic. The cut-off harmonic order q.sub.c, the level Ha and the slope value can each be varied over a predetermined range. These operations can be performed with a simple circuit arrangement involving a small number of memories. Therefore, the present invention greatly contributes to the reduction of the size and the cost of electronic musical instruments.

摘要： An electronic musical instrument which has a keyboard and creates a musical tone by striking keys of the keyboard, is provided with an operation control circuit and an adder both for effecting keyboard switch chattering prevent operation processing and touch response select operation processing, a timing control circuit for controlling the switching between the chattering preventing operation and the touch response detecting operation and the scanning of the keyboard switches to detect their status, a musical tone generator for performing a musical tone generating operation asynchronously with the keyboard switch scanning operation, the keyboard switch chattering preventing operation and the touch response detecting operation, and a transfer circuit for transferring touch response information to the musical tone generator. High-speed touch response detecting operation processing and chattering preventing operation processing which are difficult to execute by a CPU are carried out by the operation control circuit and the adder on a time-shared basis, and data is properly transferred to the musical tone generator which performs the musical signal generating operation asynchronously with the abovesaid operations, thereby implementing low cost touch response processing which is free from hardware limitations on the number of tones to be simultaneously produced and the generator assignment system. Furthermore, data for internal processing is set for two words on a time-shared basis, and touch response data which has such a natural temporal variation curve as is obtainable with a time constant circuit system is directly operated by the operation control circuit and the adder is then rendered to one-word external output data of high precision and resolution, thereby effectively reflecting the tough response data in musical parameters of musical tones to be created.
