摘要： A keyboard for a monophonic musical instrument has a plurality of touch sensitive keys which function as variable capacitors, the capacitance depending on the force applied to the keys. The variable capacitance is detected and used to produce a variable control voltage which is used to execute one or several of various control functions, such as controlling the volume of the sound produced by The instrument, controlling the cutoff frequency of a low pass filter in the output system of the instrument, controlling the amount of vibrato or other periodic modulation introduced into the sounds produced by the instrument, controlling the frequency of the vibrato or other periodic modulation, or controlling the amount of "bend" in the pitch of a sound produced by the instrument, i.e. shifting the pitch slightly from its nominal value. The variable capacitors employ a conductive elastomer which is deformed in response to the force applied to the keys. The changes in the capacitance are converted to a DC voltage which is used to control the amplitude of an output signal.

摘要： A sound effect circuit with a phase shifter producing a signal shifted in phase with respect to an input signal, a combining circuit for arithmetically combining the input and phase shifted signals to produce an output signal, an oscillator for periodically modulating a characteristic frequency of the phase shifter and a modulation control circuit. The modulation control circuit causes the modulation rate to gradually increase when modulation is manually switched on and to gradually decrease when modulation is switched off. The modulation control also causes the characteristic frequency to vary inversely with the modulation rate. The system defined by a part of the circuit producing a first output signal proportional to the sum of the input and phase shifted signals has a comb shaped frequency response curve and a part of the circuit producing a second output signal proportional to the difference between the input and phase shifted signals has a comb shaped frequency response curve inversely related to that of the summing part of the circuit. When the two output signals are fed to separate speakers, the total frequency response curve of the two systems taken together is substantially flat, but the distribution of energy in the frequency spectrum moves in space as the modulation proceeds to produce a new "stereo phase shift" sound effect. A rotary potentiometer for mixing the first and second outputs signals with each of the input signal and the phase shifted signal in selected proportion provides a third output signal with selectively variable characteristics.

摘要： This invention relates to an improved bracing structure for a stringed musical instrument of the type having lower frequency or bass strings and higher frequency or treble strings, and a bridge through which the strings are coupled to a soundboard structure. The bracing structure is formed on the underside of the soundboard and serves both a mechanical-structural and a mechanical-sonic, or acoustical function. The structural function is to protect the soundboard from damage resulting from the torsional forces resulting from the pull of the strings on the bridge, which forces are transmitted through to the soundboard. This function is accomplished by a torsion bar positioned substantially in axial alignment with the bridge, torsional forces applied by strings to the bridge being transmitted through the soundboard to the torsion bar, and a framing bar structure physically connected to and acting through the torsion bar to distribute the torsional forces from the bridge area of the soundboard. These torsional forces may be distributed by the framing bar structure to the elements structurally supporting the soundboard or may be distributed only over a larger area of the soundboard.The sonic or acoustical function is accomplished by a pattern of acoustical bars attached to the underside of the soundboard and oriented in a predetermined pattern which pattern is adapted to permit the soundboard to vibrate optimally at different frequencies in different zones thereof and by a boundary structure which limits the zones of the soundboard which may vibrate at selected frequency ranges and inhibits the formation of antinodes outside of these limited zones. The boundary structure includes, for the preferred embodiments of the invention, peripheral bars generally located at a boundary of the limited zones in which vibration at selected frequencies occur and stiffening bars positioned in regions where vibrations are not to occur.

摘要： A circuit for producing a chorus effect in an electronic musical instrument. The circuit includes N separate channels, where N is an integer greater than one, with each channel having an analog delay line to which a tone signal is applied. Each delay line frequency modulates the applied tone signal at a subaudio rate in response to changes in the frequency of clock pulses applied to the delay lines. The delay variations in one delay line are out of phase with the delay variation in every other delay line by a selected amount which is normally 360.degree./N. Clock pulses are generated by means including a nonlinear circuit to compensate for the nonlinearity in the frequency interval between tones in the musical scale. The outputs from the delay lines after filtering of the clock frequency components are utilized to produce the desired chorus effect output from the instrument. Each of these outputs is applied through a separate voltage controlled amplifier (VCA) with a common control voltage being utilized for all of said VCA's. The magnitude of this control voltage is determined by the amount of light from a light source which impinges on a photo-resistive device controlled by a mask positioned between these elements.

摘要： An integrated circuit has a shift register, driven by a source of clock pulses, for sequentially energizing each of a set of selectively activated switches. Each of the switches connects an analog input signal to the input of an individual sample-and-hold unit, the outputs of which are available at output terminals of the circuit. The outputs of the sample-and-hold units represent the amplitude of the analog input signal, sampled at the rate of the clock pulses applied to the shift register. The analog input signals of selected outputs are modified selectively.

摘要： This invention relates to an improved neck-body joint for a guitar-like musical instrument which joint minimizes the possibility of relative movement between the neck and body and permits the neck to be pitched at a desired angle relative to the body without weakening either element. The firm joint is achieved by (a) providing a tongue which extends from the end of the neck and a recess in the upper surface of the endblock, the recess being positioned and sized so as to permit the tongue to fit snugly therein and be secured therein when the neck and body are fully assembled; (b) providing a dove-tail projecton on the end of the neck which mates with a dove-tail channel formed at the mating end of the headblock and (c) reinforcing the body at a point substantially under the last fret of the fingerboard, such reinforcing being accomplished by securing first and second reinforcing bars respectively to the inside surfaces of the soundboard and the bottom board of the body at the point under the last fret with these bars extending from one sidewall of the body to the other, and attaching reinforcing bars to each of the sidewalls, the bars extending between and being connected to both the first and second reinforcing bars. The desired pitch angle for the neck is achieved by utilizing a soundboard having a large angle curve, the neck being pitched such that its upper surface is in a plane tangent to the curvature of the soundboard at the back end thereof.

摘要： An improved frequency sensitive circuit capable of adjusting one or more of its parameters in order to shunt an adjustable amount of electrical signal to a current sink, thereby controlling the amplitude of the signal. The frequency sensitive circuit is connected to the wiper of a potentiometer that is placed across the inputs of a difference amplifier in order to control the peak value of the cut or boost in the signal. The frequency sensitive circuit includes a shunt impedance connected between the wiper of the potentiometer and the current sink. A resonant circuit is connected to the impedance and is tuned to an adjustable resonant frequency. A compensation circuit, such as a difference amplifier referenced to the wiper, couples the output of the resonant circuit to the shunt impedance so that the impedance of the frequency sensitive circuit approaches infinity as the frequency of the electrical signal is displaced from the resonant frequency. As a result, the frequency sensitive circuit has substantially no effect on the overall amplitude of the electrical signal at frequencies widely displaced from the resonant frequency.

摘要： An electronic musical instrument has a keyboard equipped with apparatus for developing a voltage in response to the momentum of operated keys of the keyboard, which voltage is employed to control the amplitude of the sounds produced in response to each key depression. The amplitude is dependent partially upon the momentum of the key depression and partially upon the amount of time since the previous depression of the same key. An envelope generator operates in response to depression of a key and has a charge circuit for controlling attack and decay of the envelope. The discharge circuit is controlled partially by the pitch of the note selected by the depression of any given key of the keyboard. The envelope produced by the envelope generator controls a unit which functions as a combined modulator and filter, closing a path between an audio source and an output system and varying the width of the band-pass provided for the signal from the audio source in response to the amplitude of the envelope. The wave shape of the signal supplied to the output system is also modified in response to the amplitude of the envelope.
