Description

200426779 V. Description of the invention (l) [Technical field to which the invention belongs] The present invention is a digital music (M I D I) playback system, particularly a digital music playback system applied to a portable device. [Previous Technology] With the continuous development of audio technology, digital products have gradually entered people's lives. Because digital music uses digitized audio, it has achieved a very desirable sound effect and quickly replaced the traditional analog audio. An important source of audio data is MIDI: Musical Instrument Digital Interface (MIDI) files. International electronic musical instrument manufacturers reached a relevant agreement and formally submitted it to the M I D I Manufacturers Association in 19g8, which became an international standard for digital music (General MIDI). General MIDI specifies the communication protocol specifications for transferring data between electronic musical instruments and computer hardware and electronic musical instruments. General MIDI enables electronic synthesizers from different manufacturers to send and receive music data to each other. With the implementation of General MIDI, computers have become the control link between electronic synthesizers, and a large amount of computer software has appeared on the market that can record, store, edit, and play music scores (note tables or note sequences). However, these hardware M I D I synthesizers or sequencers are not portable. It is difficult to move and is not conducive to use. Musicians can only perform M 丨 D 丨 sequencing in audio studios. At present, some portable devices, for example]) 丨% 111 £ 111, ^ 11 ^ 11 ^ 11, etc. do not have midi playback function. Although-some portable devices can play MIDI files, but most of them are single-channel formats, and cannot be played simultaneously with other channels to achieve the effect of polyphonic sound. Although mobile phones with polyphonic sound

This function is available, but it is not edited or edited. Therefore, it is an important development direction of how to portable and be able to synthesize and edit sound. [Summary of the Invention] In view of this, the present invention is a music playback system, which is applied to portable albums, and can be in a multi-channel format. Therefore, to achieve the above purpose, the present invention includes an input receiving module for adjusting The module, according to the user ’s input and adjusts the additional functions of the channel, edits the user ’s input, edits the user ’s adjustments and edits, and broadcasts various digital ID music provided by the present invention. Musicians can easily edit music, modify rhythms, and so on, and modify files has the advantage of small capacity. Therefore, the present invention can also be from multiple channels at the same time (usually 128). Below: [Embodiment] Provides sound modification function, can not implement MIDI playback function in the sound equipment, edit additional effects, etc., is now portable

Page 5 To solve the above problems, a digital device is proposed, which can edit the sound and play the sound. The digital music playback system mentioned by the user receives the input from the user, and the channel inner valley ’opens a corresponding number of channels. The module can be edited, which is used to play the module according to the added music effect and root the corresponding MIDI file. The music playback system can not only play and modify the M I D I music, especially for the audio signal, including changing the control signal, and storing it after the exchange. At the same time, the M I M can be easily obtained from the Internet. The output polyphony music supports MIDI format instrument sounds. Technology ’is illustrated with the illustration

200426779 V. Description of Invention (3) '-Audio technology mainly includes digitization, speech processing, synthesis and recognition. The original audio data is generally edited before it can be used. Through,, ’flat series can realize various sound mixing and eliminate or reduce changes in sound. 々With the MIDI standard, the digital products of different instrument manufacturers can be compatible with each other and connected to use. This digital platform can create, edit, modify, store and play. Musicians can build individuals to work with 101 music. ^ i finished, music creation. MIDI also provides a method for digitally compressing music, capable of storing and playing music works with high quality. One-: Qiu Qi organizes the required sounds & rhythm, notes, etc. of a piece of music in a row to make the sound source sound. It is actually the second person who has recorded the music to make the sound. The essential content of the m 1 d 1 file is actually within the sequence; The composition Ding Tai Li Pi m &# 伴 ^ Yue Xuwei records his creation, just as if he took it in. The sequencer remembers the lion! Information instead of Λ 'Λ in Γ, and Λ is stored in RAM, and then saved to cf, "肀 is used for the storage of water long time. 1 丨 in human style, stores Mm information." Large Most sequencers can be taken on a file grid in a variety of ways, using the market to create their own, etc., which requires high-quality sound: = obtained on the Internet 'or recording. Shou can rent special recording equipment for multimedia playback below Player (ΜΜν, detailed description. MMV MIDI player ^ I) as an example, the present invention is detailed to be able to play GM (Genera 1

200426779 V. Description of the invention (4) " ---- MIDI) format file or standard ^^ format file software player. The standard MIDI format is a standard music format for recording and playing music. In Dragon V, the digital music playback system of the present invention is installed, so that OV has more functions: such as editing music processing and multi-channel mixing. Please refer to the group architecture V, and say that: as in the digital music input mentioned in the present invention, the addition function is enabled, and the realized 16 channels are switched by switching the Pan power negative channel. By its additional energy, in the content (U access, module 110, which is used to receive all user input humane attachments Γ = ^ inner valley includes the user & all input forms <, for example, select through: additional functions, editing Additional sound effects 1 level switching and other forms of input: including: 椹 3 Yunya 5 weeks is the additional function of §Hai channel, the channel is connected to this, select the instrument, change the channel volume, solo ii; r: change function, Pan function, etc .. JingLiNeng can mute all the selected channels by muting other unselected channels with: π, and you can A / cut all the additional channels. Function. It moves in the same direction and moves the stomach to the left and right. The system includes a plurality of tones: "In other words, there are 16 types of musical instruments that can be played. Function. In addition, the user can select a channel and adjust it, and its additional functions can be requested by the user

200426779 V. Description of Invention (5) Adjustments are required. (3) Function editing module 130, which is used to edit additional music effects according to the editing content input by the user. The editing content input by the user includes: rhythm adjustment, tone adjustment, master volume adjustment, filtering function, effect function, preset Function, drive selection, etc. Among them, the filtering function can cut off all the changes during the music playing process to keep the original effect of the sound. If the filtering function is activated, the system will not process any changes to the current sound program. This effect function allows users to edit MIDI music, including: monaural, stereo sound, Dolby surround, preset functions, etc. The preset functions further include: Hall, Classical, Rock, Pop, and so on. The preset function can be restored to the original order with 11} 1 audio data or standard. Different drivers will provide different audio data in the instrument. With the driver selection function, the user can select a suitable driver for playing MIDI. Once the driver is selected, the system will load the driver data for all channels of the song.
