Abstract: Settings of a table as to correspondence between performance parts and tracks can be changed as desired through operation by a user. If the settings of the table have been changed when a visual performance guide is to be provided for a given performance part, the changed settings are automatically referred to so that performance data of a particular track related with the given performance part is selected and used for the performance guide. Namely, whenever the settings of the table are changed, corresponding relationship between tracks and performance parts can be newly set in an automatic fashion, so that it is possible to eliminate a need for a user to repeat a same cumbersome changing operation each time an automatic performance is to be initiated.

Abstract: In a fingering information analyzer, tone pitch information indicative of each tone pitch of a series of musical notes supplied from a flexible disc or a performance information memory is analyzed to produce fingering information indicative of a performance finger for each of the musical notes. The fingering information is mixed with the tone pitch information and memorized in a fingering memory. When the fingering information is reproduced, a performance finger for each of the musical notes is determined in accordance with a changing direction or variation width of the tone pitch information continual in time series and a changing condition of white and black keys based on the tone pitch information. The tone pitch information and fingering information memorized in the fingering memory is read out in accordance with progression of a musical tune and adapted for performance of the keys on a keyboard and for indication of the performance finger.

Abstract: Indicators are provided in corresponding relations to individual keyboard keys. For each of plural phrases of a given music piece, information is supplied that represents at least the highest-pitch note to the lowest note in the phrase. During performance of the music piece and on the basis of the supplied information, the indicators, for each phrase, indicates all notes within a range from the highest-pitch note to the lowest note of the phrase. Thus, the player can easily position his hands over accurate keys and thereby can comfortably carry out performance operations for each phrase. Notes to be performed in each phrase after a first note corresponding to predetermined performance timing in the phrase may be indicated in different manners (for example, by varying degrees of brightness) depending on performance timing differences, from the first note performance timing, of the notes.

Abstract: An electronic musical instrument comprises a plurality of keys being displaceable relative to a support member therefor in response to depression thereof. A CPU detects velocity of depression of each of the keys from displacement of the each key caused by depression thereof, and also detects a pressure force or an impact force with which the each key urgingly contacts a stationary member at or near termination of depression of the each key. The CPU is responsive to the detected velocity of depression and pressure force or impact force, for determining initial touch information for a musical tone to be generated or at least one musical tone parameter, and for controlling the musical tone to be generated, based on the determined initial touch information.

Abstract: A detector is provided which generates detection signal that represents a value varying in response to the movement of a key operated on a keyboard. The key operating style employed for the operated key is reflected in subtle, dynamic action occurring in connection with the operated key during depression of the key. For instance, if the key operating style for the operated key has more staccato factor or characteristic, then the action of the operated key will present nonlinear characteristics relatively remarkably. Thus, the key operating style for the operated key can be determined on the basis of time-varying values of the detection signal, and by controlling tone depending on the determined key operating style, it is possible to achieve good-quality tone control, well reflecting subtle differences in key operating styles such as staccato, tenuto and the like, which is difficult to achieve with the conventional touch control techniques.

Abstract: An automatic performance device has a RAM for storing automatic performance information formed of time information and performance information containing time change information. A CPU instructs updating of an automatic performance position within the automatic performance information measure by measure. In response to the instruction, searching is made of the head location of a desired measure in the automatic performance information, by reading out the performance information of the automatic performance information from the RAM, based on the time information, and counting time corresponding to each measure in the performance information read out to obtain a count value of the time. The reading-out is continued until the head location of the desired measure is searched out. When the time change information is read out during the searching, the count value of the time corresponding to one measure in which the time change information is read out, is corrected, based on the time change information.

Abstract: A CPU extracts a specified number of tones, in order of lower pitch from among notes of pressed keys and then determines a chord based on the specified tones so that a musical relationship can be established between the tones corresponding to the depressed keys and the generated chord, thus eliminating incongruity in the performance. In addition, since the chord detection is made based on the specified number of tones, there is no need to play all the constituent notes of the chord. Moreover, by storing chord pattern abbreviations in chord table memory, chords are detected in the manner that of frequently occurring abbreviated chord patterns are prioritized over infrequently occurring chord patterns.

Abstract: A key-to-be-depressed designating apparatus, employed in a keyboard-type electronic musical instrument, is suitable particularly for novice keyboard-instrument players, and this apparatus is designed to automatically and sequentially designate the keys to be depressed in accordance with the predetermined tune. This apparatus includes a read-only memory (ROM) which pre-stores automatic performance data, a central processing unit (CPU) and a plurality of guide lamps. These guide lamps are disposed along with the keys of keyboard, so that they are sequentially turned on and off so as to designate a key to be depressed in accordance with the automatic performance data read from the ROM under control of the CPU. If the designated key is actually depressed by the performer within the predetermined period of time concerning its correct key-depression timing, key-to-be-depressed designating operation made by the guide lamps is continued. If not, such key-to-be-depressed designating operation is terminated.

Abstract: An automatic accompaniment apparatus for an electronic musical instrument comprises a performance data generating device, a key-count detection device, a chord data memory, a chord data decision device and an accompaniment performing device. The performance data generating device generates key depression data and tone pitch data in response to a performance operation. The key-count detection device detects a count of depressed keys in the performance operation based on said key depression data, and generates data representing the count of depressed keys. The chord data memory stores previous chord data representing a chord type and a root note, and the previous chord data corresponds to a performance operation played previously. The chord data decision device detects a chord pattern corresponding to said count of depressed keys and said tone pitch data and, when said count of depressed key corresponds to a specific count, decides chord data based on said chord pattern and said previous chord data.

Abstract: The automatic accompaniment device is constructed such as to convert tone data of a preset accompaniment pattern according to inputted or detected chords so as to generate matched accompaniment sounds. The tonality of performed music is detected by comparison between constituent notes of detected 7th chord or 7sus4 chord and those of a preceding detected chord, based on occurrence of note coincidence therebetween. A particular note name is determined for adjustment based on the detected tonality. The device designates a key code of chord constituent note corresponding to the determined note name so as to adjust the key code, thereby performing automatic performance in conformity with the tonality in natural manner.

Abstract: An automatic accompaniment apparatus is adopted to a keyboard-type electronic musical instrument. Herein, the chord constituent notes and bass note of the subharmonic chord (or fractional chord) are detected and separated from the notes which are designated by the performer who depresses the keys of the keyboard. In response to certain chord note, particularly root of the chord, the desirable chord pattern (or chord type) is selected from the predetermined chord patterns memorized in a data table. This data table can be memorized with relatively small memory capacity. Thus, it is possible to accurately detect the subharmonic chord with small memory capacity. Then, the desirable subharmonic chord is automatically sounded as the accompaniment in accordance with the selected chord pattern and the detected bass note.

Abstract: In a case where a fill-in pattern is temporarily inserted during an automatic performance, not only a main pattern to which the performance pattern should be shifted but also a main pattern which has been performed immediately before are taken into account and a fill-in pattern is automatically determined in accordance with a combination of the two main patterns. In a case where an introduction pattern is inserted at the beginning of the automatic performance, an introduction pattern is automatically determined depending upon which main pattern is performed after the introduction performance. In a case where an ending performance is inserted at the end of the automatic performance, an ending pattern is automatically determined depending upon which main pattern has been performed immediately before the ending.

Abstract: In an electronic musical instrument capable of producing a key touch feeling resembling one in playing the piano by the provision of a hammer which is interlocked with a key, key-on data and touch data are generated in response to downward displacement of the key. In this type of electronic musical instrument, key-on data and touch data are also generated when the hammer is displaced upwardly and downwardly due to bounding of the hammer independently of the movement of the key. A touch control characteristic is established usually by using touch data generated in response to key-on data. When, however, second key-on data has been generated within a predetermined length of time after generation of preceding first key-on data, a touch control characteristic for the second on data is established by using first touch data generated in response to the first key-on data.
