Modular Synthesis

Eurorack can be overwhelming. This section cuts through the noise with practical guides — from understanding the signal chain to building systems that actually make music, not just demonstrations.

Your First Eurorack System: What You Actually Need

The beginner Eurorack advice online is dominated by expensive "dream systems" and endless module debates. This guide takes a different approach — the minimum viable system that teaches you modular thinking without bankrupting you, and a clear path to expand it as you learn.

Semi-Modular vs Full Eurorack: Where to Start

Semi-modular instruments like the Behringer Neutron or Moog DFAM can be a smarter first step than diving straight into Eurorack. Here's why — and when you've outgrown them.

Key Concepts

Module Type

VCO — Voltage Controlled Oscillator

Generates the raw waveform. The sound source at the heart of any patch.

Module Type

VCF — Voltage Controlled Filter

Shapes the tone of the sound by cutting or boosting frequency ranges.

Module Type

VCA — Voltage Controlled Amplifier

Controls the volume of a signal, typically opened and closed by an envelope.

Concept

CV — Control Voltage

An electrical signal (usually 0–5V or ±5V) used to control parameters on other modules.

Concept

Envelope (ADSR)

Attack, Decay, Sustain, Release — a time-varying control signal typically used to shape amplitude.

Concept

LFO — Low Frequency Oscillator

An oscillator running below the audio range, used to modulate other parameters over time.
