In this paper, a realtime MIDI controller is designed using leap motion. The controller makes virtual MIDI port on Windows that it is connected to the port and protocol for communication with DAW or VST. It is converted MIDI data when it is detected a real time the position and shape of hand. This converted data transfer MIDI port by MIDI CC(Control Change). Therefore this controller has the purpose to support flexible MIDI input function than existed MIDI controller.

The Musical Instrument Digital Interface (MIDI) file format is a typical format for dynamic music that can be used not only for playing, but also for supporting dynamic music activity, such as musical instrument practice. However, almost all of the existing MIDI applications focus only on the playing features. In this paper, therefore, we implement a MIDI file play application that supports various dynamic features such as part-play repeating certain sections that the user wants, tone and speed control while playing a MIDI file, downloading MIDI files from a server, and lastly Digital Rights Management (DRM). By supporting these features, we are confident that our MIDI application will help users who wish to practice musical instruments to do so conveniently, while effectively protecting the copyright of their purchased MIDI files.

In this paper, we present a design method of a digital filter converting humming voice melody into MIDI data and a method of adapting it to a distributed multimedia I/O server. MuX uses device-independent DLMs(Dynamic Linking Module) for the inteliace with various I/O devices, and has wave-form audio DLM and MIDI DLM for audio interfaces. In order to expand the audio device interfacing ability of MuX system, we have designed and implemented a filter transforming human voice into MIDI messages. As the methods to input MIDI data are expanded to human voice in addition to MIDI files and MIDI instrument, someone who is not good at playing instruments can also generate the MIDI data, which enables our media interfaces to be used in various applications.

Twenty one Vibrio strains were isolated from costal water and their phenotypic properties were determined. We identified bacterial isolates by using automated identification systems, Vitek and MIDI, and compared their identification results with each other. The comparison of them provided identical species information for only one isolates, TL33( V. alginolyticus). From Vitek and MIDI,16 (76%), and 6 (29%) out of 21 isolates were identified to the species level, respectively. Vitek was more useful than MIDI for identification of Vibrio species.

멀티미디어 입출력 서버인 MuX는 다양한 입출력 디바이스와의 인터페이스를 위해 장치독립적인 DLM(dynamic Linking Module)을 사용한다. 본 논문에서는 MuX 시스템의 입출력 디바이스 인터페이스 기능을 확장하기 위해서 MIDI(Musical Instrument Digital Interface)형식의 오디오 데이터를 처리할 수 있는 DLM을 추가하였다. MIDI 데이터의 특성과 MIDI 파일 형식을 분석하여 MIDI를 지원하는 디바이스와의 인터페이스를 위한 MIDI DLM(Dynamic Linking Module)과 파일을 지원하는 DLM을 설계하고 구현하였다.

The purpose of this study was to obtain the normative data of finger strength using the keyboard and the MIDI(Musical Instrument Digital Interface) software. A total of 92 college students (46 male and 46 female) were recruited from universities located in Seoul and Chungcheong province and an average age was 21.7(SD = 1.8). After the completion of demographic information, each participant asked to press the five keys both in ascending and descending manners with the maximum strength of individual finger. The velocity was obtained as an indicator for finger pressing force by using the MIDI software. Results showed that the individual finger velocity ranged between 77 to 97 (Maximum possible velocity = 127). Regarding male's velocity data, the maximum velocity was found in index finger of dominant hand(96.9), while the minimum strength was found in ring finger of nondominant hand(78.5). Female data appeared to be similar to male's one in terms of maximum strength in dominant index finger(92) and minimum strength in nondominant ring finger(77.5). It also found that the statistically significant differences(p < .05) on finger strength of all fingers between dominant and non-dominant hands except the thumbs(p < .05). The current findings serves as a "normative standard" that proves the validity and effectiveness of hand rehabilitation training program using the electronic keyboard connected with the MIDI software to enhance functional changes in hands.

기존의 작곡가, 곡명 등의 질의어로 대표될 수 있는 메타 데이터 기반 음악 검색은 음악 데이터의 양이 급증함에 따라 탐색 근거가 되는 사항을 모를 경우 사용자의 요구를 충족시켜 줄 수 없는 단점을 가지고 있다 [1]. 반면 음악의 내용을 기반으로 한 검색의 경우 이러한 제약에서 보다 자유로울 수 있다. 내용 기반 검색[2]의 연구에 있어서 음악 데이터로부터 사용자의 질의를 처리해주기 위한 멜로디를 추출해주는 것이 중요한 문제가 되는데, 데이터의 추출과 편집이 용이한 MIDI 파일이 많이 사용되고 있다. 본 논문에서는 사용자의 질의를 바탕으로 한 QBH system상에서의 음악 데이터 구축을 위해 MIDI파일에서 추출해 낼 수 있는 특징들을 이용해 MIDI파일의 멜로디 트랙 멜로디 트랙과 반주 트랙을 자동으로 구분하는 것을 목적으로, MIDI트랙에서 추출해서 이용할 수 있는 특징들에 대해 알아보고 그에 따른 간단한 분류 알고리즘의 제안과 실험 결과에 대해 소개한다.

We developed a electronic music glove (BMG) system that plays musical scores in real time processing. The EMG system interfaces with the signal coming from the controller to the sound card in the computer, The computer, according to the status of the fingers and foot switches, generates the sound signals and sends them to the speaker systems through the application C++ program and MIDI message. The EMG systems control the velocity and duration of sound and several musical performance expressions such as chorus, reverberation, rhythm, and volume. Finally, we implemented the digital drum set using: the EMG system as example.

This paper proposes a MIDI- and audio-based music genre classification method for Korean traditional music. There are many traditional instruments in Korea, and most of the traditional songs played using the instruments have similar patterns and rhythms. Although music information processing such as music genre classification and audio melody extraction have been studied, most studies have focused on pop, jazz, rock, and other universal genres. There are few studies on Korean traditional music because of the lack of datasets. This paper analyzes raw audio and MIDI phrases in Korean traditional music, performed using Korean traditional musical instruments. The classified samples and MIDI, based on our classification system, will be used to construct a database or to implement our Kontakt-based instrument library. Thus, we can construct a management system for a Korean traditional music library using this classification system. Appropriate feature sets for raw audio and MIDI phrases are proposed and the classification results-based on machine learning algorithms such as support vector machine, multi-layer perception, decision tree, and random forest-are outlined in this paper.
