Description

Touch-controlled accompaniment mixing system for live performances

The present invention belongs to the technical field of accompaniment mixing, specifically, it refers to a touch-controlled accompaniment mixing system for live performances that can provide accompaniment music, music scores and mixing, so that performers can easily obtain accompaniment music scores and corresponding accompaniment music, and can effectively adjust the music tonality, and further has the function of multi-track sound mixing.

According to the report, in recent years, due to the increasing pressure of schoolwork, work, and life, people will participate in various leisure travel or dinner activities to relieve stress. In these activities, singing or instrumental performances are often added on site to increase people's participation and fun. For example, playing saxophone, trumpet, recorder, harmonica, piano, guitar, etc., can be performed by one person, multiple people, or mixed with different instrumentalists. Therefore, when people play instruments, they usually play the chords or background music of the corresponding tracks to accompany the main melody. Since the same track has different tones due to different instruments and singers' voice characteristics, the same track can be immediately adjusted to the performer's favorite tones, allowing the performer to view the score on the screen and obtain the accompaniment music of the tones he wants when performing on site;

Because different musical instruments have different fingerings when playing the same piece of music in different keys, such as saxophone, which has more complex fingerings, it is difficult for beginners to learn it completely. At this time, if the accompaniment audio file is not in the key of the music they are familiar with, it will not match. In this way, when the key of the main melody played by the performer cannot match the key of the accompaniment music, it will cause the main melody and the accompaniment chord music to be out of harmony. To overcome the above problems, the traditional approach is to prepare audio files of different keys or for the performer to strengthen the practice of fingerings of different keys, but there is no appropriate way to overcome it. In addition, existing sheet music is mainly in paper form, and in order to facilitate collection and viewing during performance, it is usually stored in user folders, which takes up a lot of space and causes inconvenience when carrying it out. At the same time, it is also necessary to search one by one during performance, which affects the convenience and smoothness of performance.

Audio Mixing is an important tool for music post-production or live music performance. It integrates sounds from multiple sources into a stereo track or a mono track and outputs it through an amplifier. Traditional mixers for live performances are mechanical buttons, knobs or sliders to operate the mixing. Usually, during live performances, the volume, reverberation, echo or mid-high and low sound quality are mixed and integrated. Therefore, the mixer used for live performances is different from the mixer used for post-production in general recording studios to process pre-recorded digital audio. The present invention mainly discusses the mixer used for live performances. In other words, how to enable performers to obtain accompaniment of corresponding tones during live performances and to produce better live performance music effects is what current live performers expect and what the present invention intends to explore.

In view of this, the inventor of the present invention has conducted in-depth research on the needs faced by performers during live performances, and through years of research and development and manufacturing experience in related industries, he has successfully developed a touch-controlled accompaniment mixing system for live performances after continuous efforts, so as to overcome the troubles and inconveniences caused by the limited accompaniment effects of existing performers during performances.
