摘要： Performance data is comprised of a successive serial arrangement of note data formed with paired pitch data and note duration data and of rest data formed with only rest duration data and having no pitch data. A performance data processing apparatus judges whether a rest datum following a note datum is shorter than a predetermined duration, and in case the result of this judgment if YES, the apparatus integrates the rest datum and the note datum preceding the rest datum into an integrated note datum having a note pitch of the note datum and a note duration which is equal to the sum of the duration of the note datum and the duration of the rest datum, whereby, in case a music score is displayed or printed out based on the performance data, rests having a duration shorter than the predetermined duration are eliminated to prolong the duration of the respective preceding notes each by an amount of the duration of the eliminated rest. Thus, there is obtained a music score having inscriptions similar to those of an ordinary music score, and also there can be reproduced a performance which is free of an unnatural sense.

摘要： A musical tone generating apparatus generates musical tones based on a signal outputted from a sound source and an envelope generator. The signal outputted from the sound source is processed by a digital filter in accordance with filter information responsive to a key-on signal. Filter information generating circuit generates delay time information corresponding to the time period which the digital filter needs to process and output an inputted data. The envelope is imparted to the signal outputted from the sound source with a delay from a key-on timing which corresponds to the delay time information to realize precise envelope rise portions.

摘要： An automatic performance apparatus provides a performance data memory including plural storing areas each capable of storing different performance data independently. The performance data can be selectively written in and read from each storing area. Based on the performance data read from each storing area, a musical tone signal for an automatic performance is generated independently. When the performance data memory includes two storing areas, the performance data concerning two tunes or two parts can be stored. One of two automatic performances based on the performance data can be selectively played. In addition, two automatic performances can be also player simultaneouly, wherein a predetermined delay time can be provided between two automatic performances. Further, predetermined kinds of rhythm patterns are pre-stored in a rhythm pattern memory in order to perform the desirable rhythm pattern as an accompaniment of the automatic performance.

摘要： An electronic musical instrument efficiently uses plural tone generation channels to generate both manual performance tones and automatic rhythm performance tones. The tone generation channels normally are used for manual performance tone generation. Tone generation channels for automatic rhythm performance are selected when automatic rhythm performance is designated. The tone generation channels are selected on the basis of non-use or least significance. After a required number of tone generation channels are selected for automatic rhythm performance, musical tone channel assignment is made. When stopping of automatic rhythm performance subsequently is designated, each tone generation channel selected for automatic rhythm performance is designated to return to normal use for generation of manual performance tones.

摘要： An electronic musical instrument producing a music having plural performance parts includes a generation channel unit including plural tone generation channels, a tone generation number designating unit, and a tone generation channel assigning unit. Each tone generation channel generates a tone of the music. The tone generation number designating unit designates a maximum simultaneous tone generation number to be given to each of the plural performance parts. The tone generation channel assigning unit assigns each of the plural performance parts to one or more available tone generation channels. The number of available tone generation channels is equal to the corresponding one of the designated maximum simultaneous tone generation numbers.

摘要： An electronic musical instrument comprises an accompaniment keyboard; a memory of a relatively small capacity storing a set of accompaniment data sequentially aligned and constituting accompaniment patterns; a read-out circuit to successively read out the accompaniment data from the memory at given clock pulse timings; a judging circuit to judge whether each accompaniment datum read out indicates a predetermined specific value; a random signal generator for generating, independently of the data-reading-out timings, random signals each differing in value with time; an accompaniment data determining circuit to determine the contents of each read-out accompaniment datum when the latter is judged to indicate the specific value in accordance with the signal randomly outputted just when a judgement is made; and a tone generation determining circuit to determine the generation of the accompaniment tone based on the key depression information coming from the accompaniment keyboard and also to function, when the read-out accompaniment datum does not indicate the specific value, to generate regular accompaniment pattern. The instrument performs automatic accompaniments on the read-out accompaniment patterns with random modification of a part of the pattern. Thus the automatic bass and chord accompaniment is realized in non-monotonous, variation-rich manner without a player's temporal manipulation.

摘要： In a waveform memory, data representing a silent state, e.g., zero value data, is stored in a predetermined first address area and waveform data is stored in a second address area. In response to designation of tone generation, the data representing a silent state is read from a desired number of address locations and, thereafter, tone waveform data is read from a second address area. By this control, time during which the data representing a silent state is read out, i.e., delay time, is determined by the number of address locations and, therefore, absolute time of the delay time is not constant but corresponds to an amount progress of the address signal, i.e., its phase amount. Accordingly, phase relation in a key-on delay can be made independent from tone pitch. For realizing an ensemble effect, the above control is performed in at least two channels in such a manner that, in a first channel, tone waveform data is immediately read out in response to the designation of start of tone generation whereas, in a second channel, the number of address locations for reading out the data representing a silent state is set to a number other than zero thereby is delayed from the designation of start of tone generation.
