摘要： A divider keyer circuit arrangement for a synthesis organ utilizing four integrated circuit chips to generate the notes for a 61 key manual with 9 harmonic drawbacks or tabs. On-chip cross wiring and the use of clock lines for synchronization pulses and other design techniques enable the use of four identical integrated circuit chips in standard 40 pin packages to be used to generate the full complement of notes for a 61 note keyboard.

摘要： An electronic musical instrument of a type wherein a plurality of systems are provided each system comprising memories storing respective harmonic component waveshapes which are read at the same reading rate and the read out harmonic waveshapes are suitably mixed to obtain a desired musical tone. Each system also comprises a circuit for controlling the envelope of the waveshapes read from the memories. In the first system, the envelope control is made in such a manner that the envelope will rise upon depression of a key, thereafter maintain a constant level as long as the key is kept depressed and decay upon release of the depressed key. In the second system, the envelope is controlled so that the envelope will rise in a short time and immediately decay thereafter. The respective harmonic waveshapes thus controlled in envelope in the respective systems are then suitably selected and mixed together. As an example of the envelope control in the second system is shown a structure for producing a so-called "chiff" effect by providing the fractional period during which the envelope rises and subsequently falls at the attack portion of the musical tone. Desired waveshape or waveshapes are selected from among the harmonic waveshapes controlled in the envelope in the second system for mixing with the harmonic waveshapes read from the first system. By this arrangement, amplitudes of the frequency components of the selected harmonic waveshapes are emphasized during the fractional period.

摘要： A sample hold arrangement for a key signal in an electronic musical instrument in which a keyboard circuit generates a voltage corresponding to a depressed key. The keyboard circuit is connected at its output terminal to an input terminal of a comparator. An output terminal of the comparator is connected to a memory capacitor and a buffer circuit through two gates connected in a series with one another. An output terminal of the buffer circuit is connected, in turn, to a second input terminal of the comparator, and one of the two gates is connected with its control electrode to a detection circuit. A circuit closing signal is generated by the detection circuit when the potentials of the two input terminals of the comparator become substantially equal. The other one of the two gates is connected with its control electrode to an output terminal of a keying signal generator which generates a keying signal of the keyboard circuit.

摘要： A keyboard operated electronic musical instrument such as an electronic organ is disclosed which generates a musical tone signal by mixing together two different musical tone signals of different waveforms and which changes the sound of the generated musical tone by changing a the amount of mixing of the two signals. A clipping gate with a so-called sustain function is included for controlling the attenuation of an input signal as it passes to an output terminal while clipping the input signal gradually and smoothly so that the musical tone does not disappear instantly but attenuates gradually after the release of a depressed key. The input signal to the clipping gate circuit is a square wave signal, and a square wave signal derived at an output thereof is converted to a waveform other than a square wave. When the square wave signal and the non-square wave signal are used as the two different musical tone signals, an unintended change of tone is prevented by designing the system to avoid an abrupt change in the musical tone signal between a sound generated when a key is depressed and an attenuating sound generated when the key is released.

摘要： The keyboard type instrument includes circuitry for controlling an envelope generator and a voltage controlled oscillator which in sequence operates a voltage controlled filter, and a voltage controlled amplifier both of which receive control signals from the envelope generator. The keys of the keyboard preferably have a common variable conductance touch sensor or transducer associated therewith which is responsive to key depression pressure in excess of a predetermined threshold pressure to control one or more audible characteristics of the played note. In one embodiment vibrato, pitchbend, brilliance and volume of the note are controllable. Associated with the keyboard is selection means including a plurality of audible characteristic selectors and variable means delimiting the range of the audible characteristics. The playing of a note at less than the threshold pressure provides the usual audible pitch and applied pressure above the threshold pressure introduces one or more of the audible characteristics at an intensity that is dependent upon the applied pressure and the setting of the variable control means associated with the keyboard.

摘要： An improved system is provided for automatically playing bass notes for root and fifth parts of manually held accompaniment chords, including diminished and augmented chords, and for performing pedal sustain keying functions. Latching circuits are provided which respond to actuation of playing keys or pedals and which store the response to the last pedal actuated. The system also includes circuitry for keying bass tones for actuated pedals and for the root and fifth parts of manually played chords. This circuitry includes a set of gates which are each enabled by an associated latching circuit, inhibited by other latching circuits, and inhibited by outputs from other operated gates. The system further includes keying bus sensing and controllable ratio frequency dividers to cover a multiple octave range and to reduce the number of pins required for an integrated circuit pack to implement the system.

摘要： In an electronic musical instrument, an actuation of a key switch produces a key address code corresponding to the key switch. This key address code is stored in a key address memory. A tone clock pulse corresponding to the key address code is selected from among a plurality of tone clock pulses. A musical tone wave shape memory stores in analog a wave shape to be reproduced. The musical tone wave shape is read from this wave shape memory at a reading rate corresponding to the tone clock thus selected. Attack and decay of the musical tone wave shape envelope are stored in analog in an envelope memory. When the key address code is stored by the actuation of the key switch, a clock pulse is selected to read out the attack wave shape portion at a reading rate corresponding to this clock pulse. When the key switch is cut off, another clock pulse is selected to read out the decay wave shape portion at a reading rate corresponding thereto. The read out output of the envelope memory is applied to the voltage control terminal of the musical tone wave shape memory thereby causing the musical tone wave shape memory to produce from the output thereof a musical tone wave shape with the desired envelope.

摘要： Combined footage stops are implemented in a computor organ of the type wherein musical notes are produced by computing successive sample point amplitudes of a musical waveshape and converting the amplitudes to sound as the computations are performed in real time. Each waveshape amplitude is obtained by evaluating those Fourier components comprising an incomplete set of harmonics for a first footage voice, and the fundamental and several low order odd harmonics of a voice of lower footage. In a preferred embodiment, an incomplete 8-foot harmonic series is employed, together with the first four odd harmonics of a 16-foot series. The 8-foot harmonics correspond in frequency to even harmonics of the 16-foot series. The missing 8-foot components are ''''reinstated'''' by the listener''s ear. As a result, the combined voice is perceived just as though separate, complete spectra had been used to generate the waveshape. To implement shorter footage stops, certain of the 8-foot harmonics are excluded from the waveshape computation. For combined voices including shorter footage stops, the sum of the harmonic coefficients associated with the concurrently selected stops are used in the component calculations.
