This compact seminar surveys established techniques for analog audio synthesis. Participants will explore the electrical analogs of musical events, the parameters of electronic sound, and the use of control voltages (e.g., envelopes, gate, and trigger signals). Key topics include the theory of basic signal processing, filtering concepts, and modulation techniques.

Particular emphasis will be placed on subtractive sound synthesis, waveshaping, amplitude modulation (AM), frequency modulation (FM), and ring modulation. The seminar also integrates theoretical aspects and performance practices, focusing on their implementation using modular analog synthesizers. Students will configure patches to program electronic sounds and manipulate musical variables to achieve desired sonic and aesthetic outcomes. The aim is to build up a basic understanding of modular synthesizer, how they work and how to use them.

The course revolves around the MK Sound Eurorack modular system and includes both theoretical and practical components. Participant numbers are limited, and registration operates on a first-come, first-serve basis.

Course Content

The course combines theoretical lectures and hands-on practical exercises to provide students with both foundational knowledge and applied skills. The structure includes:

  • History and foundations of electronic music (key developments, theoretical principles, significant works)
  • Fundamentals of electronics (basic electrical principles and components for audio synthesis)
  • Hands-on training with modular synthesizers (patching, signal routing, subtractive synthesis)
  • Voltage control and sound design (oscillators, filters, amplifiers)
  • Modulation techniques (AM, FM, ring modulation, waveshaping)
  • Timing and sequencing (sequencers, gate signals, rhythmic modulation)
