Electronic keyboard instrument and free playing method thereof

Abstract

The invention relates to an electronic keyboard instrument and a free playing method thereof. The electronic keyboard instrument comprises a panel, a keyboard with keys, a circuit board arranged in an outer shell and a loudspeaker, wherein the keyboard is electrically connected with the circuit board and the loudspeaker; the circuit board comprises a microprocessor, and a special software program is fixed in the microprocessor, and any key of the keyboard can rapidly and multidirectionally switch back and forth among different tones through a switching circuit electrically connected with the circuit board and the special software program in the microprocessor. Compared with the prior art, by the free playing function, an electronic organ not only can play the special skill tones of various real instruments, but also can realize rapid and accurate tone seamless switching. By the use of real skill tone sampling, performance becomes much closer to the feeling of real instruments. The invention has the characteristics that (1) the special skill tones of various real instruments are played freely; (2) the tones can be switched by directing using the keys, and the switching is rapider and more convenient; and (3) the tones have more layers, and the switching of the tones is more accurate.

Description

technical field [0001] The invention relates to an electronic keyboard musical instrument, in particular to an electronic keyboard musical instrument which can be freely switched through keyboard keys and a free playing method thereof. Background technique [0002] Existing real musical instruments use different performance techniques to produce various timbres, such as: tremolo of stringed instruments, artificial overtones of electric guitars, timbres of basses and muffled tones of wind instruments. In order to achieve the special performance effects of various real musical instruments, the electronic keyboard products on the market generally have the following realization methods: [0003] 1. Store the timbre samples of different performance skills of the same instrument in different timbre positions, and realize different performance skills by switching timbres during performance. For this method, because a piano generally has hundreds or even thousands of timbres, it is...

AI Technical Summary

Problems solved by technology

For the method of strength layering, because the player's hand is often unable to precisely control the strength, there are the following deficiencies: A. Difficult to control; easy to mis-trigger, that is, false triggering due to inaccurate strength control near the critical strength value; B. Number of timbres There are relatively large limitations: generally only two layers of timbre are controlled, the dynamics below the critical value are normal timbres, and the dynamics above the critical value are special technique timbres (multi-layered timbres can be divided into layers, but because the dynamics are difficult to control accurately, generally only 2 layers of timbres are used) )

The pitch bend wheel can simulate the timbre produced by performance techniques such as guitar bending and vibrato, and the tremolo wheel can simulate the vibrato timbre of various musical instruments, but they are all simulated performance techniques and do not use real technical timbre samples, so the timbre is not realistic. It can only imitate the general effect; the aftertouch control is to record the information of the key-touch behavior after pressing the key (such as changing the force of pressing the key after pressing the key to control the depth of vibrato, etc.), in order to achieve certain performance techniques (such as Vibrato), which is also a simulated performance technique, without sampling sounds using real techniques, the effect is not realistic enough, and continuous performance cannot be achieved
