Electronic instrument tone selector and selection method {APPARATUS FOR SELECTING TONE COLOR FOR ELECTRIC MUSICAL INSTRUMENT AND METHOD THEREFOR}

The present invention relates to a tone selection device and a method for selecting an electronic musical instrument, and more particularly, to an electronic instrument (keyboard) and a sound source module electrically connected to them and stored in a sound source chip embedded in the sound source module when playing the electronic musical instrument. To select an instrument sound (voice) and output the sound of the instrument (sound) through the speaker, the electronic instrument tone selection device and selection method for playing a variety of musical instruments with electronic instruments.

Electric musical instruments, such as electronic pianos and electronic organs, are generic terms for musical instruments that make the sound of a musical instrument sound through a speaker. Electronic instruments consist of a speaker system, a device that activates it, a device that obtains electrical vibration, a performance device, and a device for adjusting or synthesizing a tone or volume (http://dev.cein.or.kr/cyber_e/e6). / eum / eu-5 / Western Instruments.htm).

Such a conventional electronic musical instrument was also called a synthesizer with all necessary devices. However, increasingly, each device provided in the electronic musical instrument is separated into a separate module or device, and only a keyboard (keyboard) for playing is used as an electronic musical instrument. In particular, a keyboard without a sound source is called a master keyboard to distinguish it from a synthesizer equipped with all the devices necessary for performance, such as a sound source device or a sound module.

To play using the master keyboard, a separate speaker system and a sound source module that synthesized or stored the instrument's timbre or volume were required.

Meanwhile, with the development of computers, electronic instruments have been used using computers. In order to play an electronic musical instrument, especially a master keyboard (keyboard) using a computer, the computer required a sound source module (for example, a sound card) and an interface connecting the computer and the master keyboard.

When playing with an electronic instrument (keyboard) in this way connected to the computer must be equipped with a computer, so it was impossible to play using the electronic instrument in a place where the computer is not equipped.

On the other hand, the electronic musical instrument was connected to the sound source module and played as an electronic musical instrument. However, since the sound source module itself contained a MIDI controller for selecting an instrument sound, there was a problem in that the number of instruments that could be played was limited. In order to be able to play other instruments, there was a problem in that the stored memory was separated from the sound source module so that the type of instrument could be selected, and the memory in which new MIDI data was stored was reinstalled.

In addition, a part of the synthesizer has an editing function consisting of several buttons and a display window to control the sound source, or provide a key inserting part in the synthesizer, insert a card key into which the specific sound data is edited and stored, and insert the card key into the key inserting part to use the sound data. Therefore, the method of controlling the sound source was intended to be widened, but these methods had limitations in editing the timbre data, and the editing work itself was difficult.

In order to solve this problem, the need for an independent sound source control device or a tone selector separated from the electronic musical instrument and the sound source has greatly increased.

The present invention is to solve the problems of the prior art as described above, while being independent of the electronic musical instrument and the sound source module, the tone selection device of the electronic musical instrument which can select different musical instrument sound of the sound source module according to the performance of the electronic instrument and It is an object to provide a selection method.
