摘要： An electronic musical instrument comprises a key on-off memory for storing the on-off state of the respective keys, and at a time counter for counting the lapse of time after release of the respective keys. The time counter inhibits generation of the musical tone signal corresponding to the key when the conditions that predetermined time is elapsed after the key release and that the key-off state is stored in the memory are satisfied. This inhibition is separately conducted with respect to the keys. Thus, it can remarkably prevent noise when the tone should not be produced.

摘要： An electronic musical instrument having an automatic performance device includes a memory storing in addition to automatic performance data, envelope control data for controlling envelopes of automatic performance tones to be generated. The envelope control data has two logical values and is used for controlling the envelope of the tone at the decaying portion. The value "0" designates a gradual decay and the value "1" designates a quick decay. The automatic performance tones are respectively imparted with either of the gradual and the quick decay shapes suitable for the time intervals between the generated tones in the designated automatic performance pattern.

摘要： A keyboard electronic musical instrument comprises a note information processing device capable of processing note information required for automatic arpeggio and automatic bass performances. This note information processing device includes a generation circuit for generating a plurality of note information representing a plurality of notes to be sounded in relation to the key depression, a selection circuit for sequentially selecting a note information designating a note to be sounded from among the plurality of note information from the generation circuit in accordance with a predetermined priority order; an output circuit for delivering out the note information selected by the selection circuit, the selection at each sequence being conducted dependent on the selection at the preceding sequence. The selection circuit includes a first selector which selects note information of higher (or lower) notes than the note information outputted at the preceding sequence and a second selector which selects note information of the lowest (or highest) one from among the information selected by the first selector. The note information processing device is used commonly for the automatic arpeggio performance and the automatic bass performance in a time division manner.

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.
