Abstract: The author analyzes the experience of transcription of the compositions of J. Bull, C. Monteverdi, J. Bach, C. Debussy and S. Prokofiev for a synth keyboard Synthi 100 done by the Russian composers A. Artemiev, V. Martynov, Yu. Bogdanov in 1980, and released on the disc “Metamorphoses”. The author also considers the composers’ range of artistic tasks and sound solutions and the variants of work with the texture of the original compositions. The electronic interpretations, contained in the “Metamorphoses”, not only demonstrate the examples of transcribing the original text for a synth keyboard, but also illustrate the 4 criteria of electronic music formulated by K. Stockhausen: unified temporal structuring (a common temporal field), the disintegration of sound, a multidimensional spatial composition, and the equality of the tone and the noise. 
In spite of the fact that the transcription of classical music pieces for a synth keyboard was carried out by the Russian composers several decades ago, this experience hasn’t been studied yet. Probably, it is explained by the fact that the analysis and description of electronic music using traditional means is complicated, since the material under study is not noted: all transformations carried out by the interpreter are fixed only in the audiorecord. 
The analysis of transcriptions is complicated by the fact that electronic instruments are regularly upgraded and transformed, and therefore their artistic capacity is increased. The change of instruments caused the transformation of approach to music art. The article analyzes the transformation of the author’s text, the transformation of a piano texture into the electronic score, and the role of the arranger as a co-author of the composition.  

Abstract: Nowadays, computer technologies are integrated into all art forms. New artistic directions emerge which are totally based on multimedia (primarily audio-visual) instruments. The question about the role of music art in the new cultural paradigm becomes topical. Based on the example of academic music, the article considers the possibilities of using programming tools for music scores processing into a transcript. The authors consider the possible mathematical model of a piece of music which allows processing the piece of music and getting both an authentic and an experimental version. The authors analyze the set of parameters helping to form a virtual acoustic space corresponding with an artistic concept. The authors demonstrate that academic music transcript modeling using electronic sound synthesis can promote the artistic reinterpretation of the score of the piece of music. The selection of particular timber, performance and spatial parameters during transcribing helps to interpret a composition according to the artistic tasks. The use of virtual instruments also allows creating digital recordings without performing musicians. The article contains the variants of forming a virtual acoustic environment based on the example of a classical piece of music for string quartet: from a “traditional” to an “experimental, differing in musical sources positioning, a set of spatial effects and the parameters of their adjustment.
