Claims (1)

[Claims for Utility Model Registration] 1. An electronic musical instrument having an automatic performance recording mode for recording automatic performance information and an automatic performance playback mode for reproducing the automatic performance information recorded in the automatic performance recording mode, a plurality of performance operators for specifying a plurality of performance operators; a storage means for storing automatic performance information consisting of a plurality of musical tone data including pitch data input by operating the plurality of performance operators; and in the automatic performance recording mode, a setting means for setting a write start address of the automatic performance information to be written in the storage means in accordance with the performance operator operated immediately before writing the automatic performance information in the storage means; and the automatic performance recording mode. After the writing start address is set by the setting means, the automatic performance information input by operating the performance operator is set by the setting means and the writing start address is set by the setting means. a writing means for sequentially writing from an address; and when any of the performance operators is operated immediately after switching to the automatic performance playback mode, the writing means corresponding to the operated performance operator; determining means for determining whether or not the written automatic performance information is stored in the storage means; and in the automatic performance playback mode, the automatic performance information is stored in the storage means by the determination means. an electronic musical instrument, comprising: a reproduction means for sequentially reading out the automatic performance information corresponding to the performance operator from the writing start address of the storage means and reproducing the music when it is determined that the musical instrument is present. . 2. The setting means sets the write start address to the same address for the plurality of performance operators when the plurality of performance operators are operated simultaneously. electronic musical instruments. 3. The writing means writes automatic performance information including pitch data corresponding to the operated performance operator, and the reproduction means reproduces the music based on the automatic performance information including the pitch data. The electronic musical instrument according to claim 1 or 2, characterized in that: 4. In an electronic musical instrument having an automatic performance recording mode for recording automatic performance information and an automatic performance playback mode for reproducing the automatic performance information recorded in the automatic performance recording mode, a plurality of performance operators that specify at least pitches. and storage means for storing automatic performance information consisting of a plurality of musical tone data including pitch data input by operating the plurality of performance operators; and in the automatic performance recording mode, the automatic performance information is written in the storage means. a setting means for setting an information write start address in correspondence with the performance operator operated immediately before writing the automatic performance information in the storage means; and a pitch specified by the operated performance operator. a writing means for writing automatic performance information including pitch difference data indicating a pitch difference between a predetermined reference pitch; and a reproduction means for reproducing a musical piece based on the automatic performance information including the pitch difference data. The playback means sets an initial pitch of a piece of music to be played when any of the performance operators is operated immediately after switching to the automatic performance playback mode;
An electronic musical instrument characterized in that pitches of subsequent songs are set based on the first pitch and the pitch difference data stored in the storage means. 5. The electronic musical instrument according to claim 4, wherein the reproduction means sets a pitch corresponding to the first operated performance operator as the first pitch in the automatic performance reproduction mode. 6. The electronic musical instrument according to claim 4, wherein the reference pitch is a pitch written in the write start address of the storage means. 7. The storage means has a repeated performance information storage area that stores repeated performance information that can be used repeatedly according to the operations of the plurality of performance operators, and the writing means has a repeated performance information storage area that stores repeated performance information that can be used repeatedly according to operations of the plurality of performance operators, and the writing means In the recording mode, when the pitch data of the first pitch of the automatic performance information input by operating the performance operator is equal to the pitch data of the last musical tone, the pitch data is input by operating the performance operator. 7. The electronic musical instrument according to claim 4, wherein automatic performance information is written as the repeated performance information in the repeated performance information storage area in the storage means. 8. When a predetermined performance operator that generates a musical tone with a predetermined pitch is operated, the reproduction means reproduces the first musical tone of the musical piece at the pitch corresponding to the predetermined performance operator, and then, Reading pitch difference data from the repeated performance information stored in the repeated performance storage area, and reproducing the second and subsequent musical tones of the musical piece at a pitch based on the read pitch difference data and the first pitch. The electronic musical instrument according to claim 7, characterized by: 9. A foot operator operated by a foot operation, and detecting the foot operation of the foot operator and the operation of the performance operator, and based on the detection results, continuing or terminating the reproduction of the automatic performance information by the reproducing means. Claims 1, 2, and 2, further comprising: a control means for controlling;
