摘要： A tone generator system for an electronic organ, which incorporates N programmable generators (where N is less than 12, and typically 7) which forms a system having the ability to sound notes of N different nomenclature tones at one time. A microprocessor controls the assignment of particular notes to each of the programmable generators, in accordance with the played keys of the keyboard(s) (and the tab switches, in the event that a partial footage is selected). Each of the programmable generators is connected to a chain of dividers and gates which are also under the control of the microprocessor. The information ascertained by the microprocessor from the keyboard(s) (and the tab switches) is used to control the selection of gates which control the passage of tone signals from appropriate dividers in the chains of dividers to an audio output system. More than one note of a particular nomenclature can be simultaneouly gated from the divider chain of a particular programmable generator.

摘要： Music playing apparatus for playing selected musical notes in accordance with a selected rhythm pattern. A rhythm pattern is selected having a multiplicity of intervals. The rhythm pattern is repetitively reproducible and musical notes played at any interval within the rhythm pattern may be selectively played as either an unaccented note or as an accented note. Selected musical notes are played at each interval within the rhythm pattern and the pitch of a selected note is determined. The pitch of a selected note is within a predetermined range of octaves in the chromatic scale and this range of octaves may be selectively extended. A tone generator generates audible musical tones in accordance with the established rhythm pattern, the selected musical notes, and the octave band within which the selected musical notes are found.

摘要： An electronic musical instrument employing top octave synthesizer circuits (TOS circuits) for generating the musical tones to be reproduced by the instrument employs a single master oscillator common to all of the top octave synthesizer circuits for supplying the trains of clock pulses to the synthesizer circuits for their operation. To prevent phase-locked conditions from existing in the frequencies produced by different synthesizers, the clock pulses from the master oscillator are supplied to the synthesizers through coincidence gate logic circuitry which is controlled by means of a low frequency oscillator and a divider or shift register circuit to delete different ones of the clock pulses from the clock pulse signal trains for each of the different synthesizers. This causes all of the frequencies obtained from the synthesizers to be slightly different from one another, independent, and not phase-locked. This nonphase-locked system provides a more pleasing musical effect than is otherwise attainable from a top octave synthesizer system using a single master oscillator to drive more than one top octave synthesizer circuit.

摘要： An electronic musical instrument has a keyboard including a plurality of scale keys and a plurality of chord keys. Musical sounds are generated by a programmable frequency divider network capable of producing different output frequencies, depending on which keys of the keyboard are activated. A decoding means connects the keyboard and the programmable frequency divider network to supply signals which cause the programmable frequency divider network to produce different output frequencies, depending on which keys of the keyboard are activated. Means connect the scale keys and the chord keys for altering signals supplied from the chord keys to the programmable frequency divider network, depending on which scale keys are activated. On this basis, compatible chords may be generated with the chord keys for a melody being played with the scale keys. The frequency divider network utilizes lowest common multiples and prime numbers, which substantially eliminates the potential for producing dissonant sounds. The lowest common multiple and prime number approach also allows fabrication of instruments which produce diatonic scales, e.g., modified Pythagorean and modified Zarlino scales, in addition to the chromatic scale. This electronic musical instrument may be provided in a single package and consitutes a musical analog to a portable electronic calculator.
