Abstract: An electronic musical instrument capable of controlling tone pitch, tone color, volume etc. of a musical tone by a sliding operation to conduct such on effect as portamento. The instrument according to the invention can produce a control signal proportional to a sliding distance on a portamento playing actuator regardless of an initially touched position on the actuator. For producing such control signal, an output voltage from a portamento playing actuator corresponding to a finger touch position is applied to a positive input of a calculator whereas a voltage obtained by sampling and holding an output voltage corresponding to the initial touch position is applied to a negative input of the calculator. Difference between the two voltages is outputted as a control voltage from the calculator and this control voltage is utilized for controlling VCO, VCF or VCA thereby to control the tone pitch, tone color, volume etc. of a musical tone.

Abstract: An electronic timepiece is driven by a pulse motor and includes a pulse motor driving circuit which applies frequency-divided pulses for maintaining the rotational inertia of a rotor. The revolutions of the pulse motor are detected as is the load on the motor. In addition, the revolutions of the pulse motor are periodically compared with the number of driving pulse. A second hand of the electronic timepiece is continuously rotated by the pulse motor.

Abstract: Musical notes are produced polyphonically in a tone synthesizer or like musical instrument by computing a master data set, transferring data set to buffer memories, and repetitively converting in real time contents of memories to notes. The master data set is created repetitively and independently of tone generation by computing a generalized Fourier algorithm using stored sets of generalized Fourier coefficients. Computations limit tones to audible frequencies, occur at intervals short compared to musical tone periods, and circuitry is included to provide time-varying modulations of the synthesized tonal structure. Synchronizing signals included in the buffer memories provide smooth transition between the master system logic clock and asynchronous tone conversion clocks. A time shared digital-to-analog converter transforms the buffer memory outputs to individual tone channels and provides attack, decay, sustain, release and other amplitude modulation effects.

Abstract: A time correcting system for an electronic timepiece. The correcting system includes a single manually operable switch connected to a switching circuit for developing a chatter-free switching signal. A gate circuit is responsive to the switching signal for applying a time reference signal to time measuring circuitry of the timepiece. A counter is connected to receive a signal from a certain stage of a divider circuit of the timepiece for developing a count representative of the correcting mode of the correcting system. A resetting circuit resets all of the dividing stages of the dividing circuit when the counter develops a predetermined count and releases all of the divider stages from the reset state in response to opening of the manually operable switch. A first pulse generating circuit develops a pulse signal in response to termination of the switching signal before the counter develops a predetermined count in order to correct slow time.

Abstract: Tone generation in a musical instrument is accomplished by repetitively computing a Fourier algorithm using stored sets of harmonic coefficients. An alterable voice is obtained by optically reading a data card, converting the data to a data format used by the tone generating circuitry, and storing the converted data to be employed as a set of harmonic coefficients. Harmonic coefficient data is encoded on the data card by imprinting columns of opaque areas. The length of each column is measured by sequentially scanning a linear array of light sources. Insertion of the data card in an enclosure automatically initializes the reading circuitry and removing the card causes each opaque data column to be measured in turn and the result converted to a harmonic component.

Abstract: In an electronic musical instrument, such as an electronic organ, the speech characteristics of Vox Humana and similar reed organ pipes are simulated by applying a repeating series of pulse groups separated from each other, which groups each contain a short sequence of two or more pulses, to a sharp cutoff low-pass filter for converting the series of pulse groups into a sound producing signal simulative of the sound signal produced by a Vox Humana or similar organ pipe. The repeating series of pulse groups is obtained by nonlinearly combining square wave tone signals from two or more different octaves of a conventional phase-locked tone generator. The synthesized repeating series of pulse groups, one series for each note of the instrument, are applied to a single low-pass filter, or grouped and applied to a small number of filters.

The audible alarm is terminated in response to manual depression of a call time setter pin and with each depression of the pin, the alarm time detection mechanism is reset to detect a new alarm time so that the new alarm time is determined by the number of times the pin is depressed. A time indicating mechanism indicates the preset alarm time and is automatically adjusted to display the new alarm time dependent upon the number of depressions of the call time setter pin.
