Lesson 01: What Is Modular Synthesis

A first explanation of modular synthesis as a system of connected functional blocks.

Foundations

Start with signal flow, modulation basics, and first sound design patches.

  • CV vs audio
  • oscillator, filter, VCA
  • envelopes and LFOs

Theory

Modular synthesis is a way of building an instrument from separate functional blocks.

Instead of opening one fixed synthesizer with a prewired signal path, you connect the parts yourself:

  • sound source
  • timbre shaping
  • amplitude control
  • modulation
  • timing

In VCV Rack, that means the instrument is not a single plugin. The instrument is the patch.

Why It Matters Here

Modular Genesis is not centered on presets. It is centered on systems.

That matters because later lessons will depend on building behavior from smaller units:

  • sequencing
  • probability
  • feedback
  • audiovisual mapping

Patch Idea

VCO -> VCF -> VCA -> AUDIO

Practice

Open VCV Rack and identify these module roles:

  1. a sound source
  2. a filter
  3. a level control stage
  4. an output

Write down what each part changes in the sound.
