Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an electronic musical instrument that performs performances based on musical tone information from an external memory such as a ROM pack.

[Prior Art] Conventionally, there is a ROM pack in which, for example, a melody, accompaniment, rhythm, etc. are stored, and which is inserted into the pack insertion slot of the main body of an electronic musical instrument to be written into the internal memory and automatically played.

[Prior art and its problems] However, in the conventional technology, the performance information stored in the ROM pack or the like constitutes a complete song or musical tone by itself. Therefore, the information in one ROM pack can only be used to play a certain set of songs or to generate musical tones with a set tone. For example, if you try to play a song with a different tone, only the tone will be different. You have to prepare a ROM pack that stores song information, and even in the case of musical sounds, if you want to change the timbre even slightly, you have to prepare another ROM pack. In other words, if you want to have a wide variety of songs and musical tones to play, you have to prepare a large number of ROM packs, and it is not possible to satisfy all the preferences of a large number of general users.

[Purpose of the invention] This invention was made in view of the above-mentioned circumstances, and the purpose is to provide an electronic musical instrument that can play a wider variety of songs with less external memory.

[Key Points of the Invention] The present invention eliminates the need to store multiple types of performance information constituting one previously completed song or musical tone in a performance information storage means such as an external memory.
The apparatus stores a plurality of pieces of performance information of at least one type, and has an insertion means into which the performance information storage means can be inserted. The type of performance information stored in the performance storage means attached to the insertion means is specified in advance by the type designation means, and the performance information stored in the performance information storage means inserted into the insertion means is specified in advance. By selecting one of them by the selection means, the performance information of the designated type is stored in the designated area of the storage means. In this way, musical tones are generated according to the performance information stored in each area of the storage means.

As a result, by combining different types of performance information stored in each of the plurality of performance information storage means, it becomes possible to perform a wider variety of songs.

[Summary of the invention] The outline of this invention will be explained below with reference to the drawings.
