Course detail

Electronic Musical Instruments

FEKT-BPC-HELAcad. year: 2023/2024

The course focuses on analog, hybrid and digital methods of sound signal synthesis, analog and digital communication interfaces in musical electronics, principles and structure of electronic musical instruments, samplers, sequencers, effects and other musical electronics and their individual parts. Laboratory exercises are focused on working with hardware and software virtual analog synthesizers, samplers and other types of electronic musical instruments. The computer exercises are focused on the principles of sound signal synthesis in NI Reaktor and Matlab. Part of the laboratory exercises is the realization of your own synthesizer in the Reaktor program.

Entry knowledge

The knowledge of basic laws and quantities in electrical circuits is required as well as the knowledge of the characteristics of electric circuit elements, circuit behaviour with inertia elements, periodical and non-periodical signal spectra, continuous- and discrete-time systems. The student who enrols on the course should be able to use instruments for the measurement of electrical voltage, waveform generators and oscilloscopes. Furthermore, knowledge of the algorithmization of simple tasks and work in the Matlab environment are required.

Rules for evaluation and completion of the course

Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT. Up to 24 points is awarded for independent work in laboratory exercises and up to 16 points for designing own synthesizer in the Reaktor software. Up to 60 points are given for the final written examination and it is necessary to get at least 30 points for its successful completion.

Credit is awarded for completing all laboratory exercises, participating in graded computer exercises and obtaining a minimum number of points for design of own synthesizer in the Reaktor software. The minimal scope of the elaboration of particular laboratory exercises and minimum points for a design of own synthesizer are specified by a regulation issued by the guarantor of the course and updated for every academic year.  Other forms of checked instruction are specified by a regulation issued by the guarantor of the course and updated for every academic year.
