In an electronic musical instrument having a function to perform auto-playing with reading out a quantity of auto-play data every time any key is operated, a guide display comprising a plurality of display lines is made to indicate timings of key operation. In the display, measure lines ( ) and beat lines ( ) are displayed in addition to black circles ( ) for indicating operation timings. Thereby, more pieces of guide information than a conventional one can be displayed at once, besides, guidance to a far future can be given. This makes it easy to recognize the musical time pattern of the auto-play data and which beat each black circle ( ) belongs to.

In an automatic accompanying apparatus and an automatic accompanying method, the respective part structures of a plurality of basic variation patterns used as a basic accompanying pattern of rhythm are arbitrarily set by a music player. When the music player selects one basic variation pattern from a plurality of basic variation patterns to which the part structures are set in such a manner, the part structure is automatically set in such a manner that part structures of an intro-pattern, an ending pattern, and also a fill-in pattern, which are prepared for this rhythm, are made equal to the part structure of the selected basic variation pattern. The automatic accompaniment is carried out by employing the selected basic variation pattern, and the intro-pattern, ending pattern, and fill-in pattern, which own the same part structures as that of this basic variation pattern. As a result, the automatic accompaniment can be carried out while being matched with a motif of a user through the entire music. Moreover, the parameter setting operation executed before starting the musical play can be simplified.

An auto-play apparatus has an edit function for thinning out various kinds of music tone control information indicating analog control amounts contained in auto-play data pre-stored in units of parts. A data sequence of music tone control information to be edited is received to detect if the target data and its preceding and succeeding data indicate one of an increment data sequence and decrement data sequence, and thins out the target data to reduce the data volume.

Auto-play apparatus using processing to thin out tone generation control

An electronic musical instrument has a means used by a player to set a key name to which transposition is to be made and a part number to designate a transposition excluding part. Tone data in parts other than the transposition excluding part are exclusively subjected to transposition processing, and transposed tones are produced. For example, play data of a keyboard are set as a transposition excluding part, and their tones are produced in C major key as the key played. On the other hand, the keys of accompanying tones such as chord tones, rhythm tones, and the like programmed in keys other than C major key in a storage medium are transposed to C major key to produce transposed tones, allowing an ensemble play in common key.

Transposition controller for an electronic musical instrument

An electronic musical instrument having a plurality of switches is disclosed wherein a numerical value can be inputted without provision of a specific switch for inputting a numerical value. The electronic musical instrument has a tone/effect inputting mode in which, when one of the switches is operated, a tone or acoustic effect allocated in advance to the operated switch is set and a numeric inputting mode in which, when one of the switches is operated, a numerical value allocated in advance to the operated switch is set. A change-over switch is provided for changing over the operation mode between the tone/effect inputting mode and the numeric inputting mode.

Electronic musical instrument with numeric inputting function

A sequencer according to the present invention comprises: an interface circuit for exchanging externally supplied play data; a memory for storing received play data; and a panel switch for generating a signal that indicates a recording start. Recording is performed when, in response to a recording start signal from the panel switch, the sequencer, using predetermined data, automatically generates storage location data, and stores play data at the storage location designated by the storage location data. A sequencer according to the present invention further comprises: a memory for storing play data corresponding to multiple musical pieces; an interface circuit for outputting play data that is read from the memory; and a panel switch for indicating continuous reproduction. Upon the depression of the panel switch, the sequencer sequentially reads a predetermined quantity of play data from the head of each musical piece that is stored in the memory and reproduces musical tones using that play data. Then, when the panel switch is again depressed, the sequencer reads the remainder of the play data for the musical piece currently being read-out and reproduces that musical piece.

Sequencer having a reduced number of panel switches

A sequencer according to the present invention comprises: a display having multiple data input fields for entry of information items and having a capability for distinguishing or emphasizing which of the data input fields is prepared to accept input; designating circuitry for selecting an operation mode; and a control for, when a specific operation mode is selected by the designating circuitry, facilitating the entry of information items by distinguishing or emphasizing one of the data input fields where information will most probably be entered in the specific operation mode.
