摘要： In an electronic musical instrument, a plurality of component elements of a musical tone are designated by a respective plurality of manual setting elements and preset in a preset memory device. A person operating the device can select a musical tone to be produced based on the component element preset in the preset memory device or the component elements formed by the manual setting elements or any combination of such preset and manually set component elements. A visual display is used to display the amount of operation of the manual setting elements.

摘要： An electronic musical instrument having its keyboard divided into plural key ranges with musical tones being generated with tone colors which are different one key range from another. For achieving this object, the instrument comprises channel processors, tone generators, additional tone generators for the lowest (or highest) key in each key range, a common key coder for obtaining key data of depressed keys and a control circuit for supplying key codes delivered out of the key coder to only a channel processor of a corresponding key range. The key coder delivers out key data of depressed keys sequentially one key data at one time slot. According to the invention, the lowest (or highest) tone in a predetermined key range is generated with a tone color corresponding to the key range and also with a different tone color. The time slot allotted to the lowest (or highest) key is divided into two halves and a key code of the lowest (or highest) key is applied to a corresponding channel processor during the first half and is applied to a tone generator for the lowest (or highest) key after being once stored in a register. A lowest key detection circuit generates a pulse defining the second half of the time slot.

摘要： An electronic musical instrument with an automatic chord performance device is of a type in which chord tones of plural series of different tone colors in different rhythm patterns are produced. This instrument employs a memory for storing a plurality of patterns per one rhythm and for plural rhythms in order to simultaneously obtain the chord tones of plural series per one rhythm. The patterns are read from the memory as tone generation timing signals. These tone generation timing signals control the amplitudes of the envelopes of the chord tone signals. The chord tone signals thus controlled in amplitude are generated after being controlled in the tone color in each of the series.

摘要： An electronic musical instrument is of a channel assignment type and simultaneously produces a plurality of tones in automatic arpeggio performance. For that purpose, the instrument incorporates a plurality of automatic arpeggio performance channels. An automatic arpeggio performance is carried out in accordance with an arpeggio pattern. In order to simultaneously produce a plurality of automatic arpeggio tones, the instrument assigns respective arpeggio composing tones for the plural arpeggio performance channels by using an arpeggio pattern for one-tone production and a change pattern obtained by adding change information to the arpeggio pattern. Thus an automatic performance of polyphonic arpeggio is realized.

摘要： An electronic musical instrument capable of providing automatic bass and chord accompaniments, either in accordance with a program prepared by the player or in immediate response to the depressing of a minimum number of keys on lower and pedal keyboards. The programmed accompaniments proceed sequentially (in steps) with successive measures of accompaniment data being read from a memory. By making some of these measures blank in introducing the accompaniment data into the memory, therefore, the player can play desired bass and chord accompaniments by direct key depression during the blank measures. In an alternative embodiment the production of the programmed accompaniments is automatically inhibited during the production of key-responsive accompaniments, thereby enabling the player to override the programmed accompaniments at any time.

摘要： An electronic musical instrument is of a key assigner type including a key coder and a channel processor, and is equipped with an automatic bass/chord performance faculty. The key coder includes a root note memory and a chord type memory, whereas the channel processor includes a key code memory and a key-on memory. The instrument is provided with a chord note memory function rendering switch and a bass note memory function rendering switch. When the chord note memory function rendering switch is turned on, the key-on memory is not cleared after release of the keys for conducting a automatic performance of chord tones. When the bass note memory function rendering switch is turned on, the root note memory and the chord type memory are not cleared after release of the keys for conducting an automatic performance of bass tones.Thus a bass-note memorized automatic accompaniment performance and a chord-note memorized automatic accompaniment performance are independently selectable.

摘要： An electronic musical instrument is of a type in which a particular note tone and tones corresponding to the remaining notes among depressed keys are alternately and repeatedly produced in accordance with tone production timing signals having a predetermined period. The tone production timing signals are produced by frequency dividing tempo pulses generated from a tempo pulse oscillator. An alternate production control is conducted by gating alternately signal of the particular note tone and signals of other tones and delivering to a sound system. The period of the tone production timing signals can be controlled by a circuit which detects depression of plural keys.
