Basic Concept 10: Random Sources
Random voltage generators bring organic variation to synth patches. Learn how smooth, stepped, and trigger-based randomness can add life, unpredictability, and evolving textures to your sounds.
Basic Concepts
Basic Concept 9: LFOs
LFOs bring movement to synthesis by modulating parameters like filter cutoff and pulse width. Learn about waveform types, sync, delay, and how to shape modulation for evolving, expressive sounds.
Basic Concept 8: Envelopes
Envelope generators shape how a sound evolves over time – from percussive hits to swelling textures. Learn the basics of AD, ADSR, and looping envelopes, and how they control amplitude, filters, and timbre in a synthesizer.
Basic Concept 7: Waveshaping
Waveshaping alters the harmonic makeup of a waveform to create new timbres. Learn how techniques like saturation, rectification, and wavefolding shape sound, and how modulating these parameters brings movement and complexity.
Basic Concept 6: Filter Resonance
Filter resonance – also called Q or emphasis – boosts harmonics near the cutoff point, creating vowel-like tones and dramatic peaks. Learn how resonance shapes sound and brings filters to life in expressive, musical ways.
Basic Concept 5: Filter Slopes
A filter’s slope determines how steeply it removes harmonics beyond the cutoff point. Learn how 1-, 2-, 4-, and even 8-pole filters shape sound with increasing intensity – from subtle roll-offs to dramatic tonal sculpting.
Basic Concept 4: Filter Modes
Filters shape sound by removing or reducing harmonics. Learn how low-pass, high-pass, band-pass, and notch filters work – and how adjusting the cutoff frequency creates dramatic changes in tone and texture.
Basic Concept 3: Noise
Noise in synthesis comes in many "colors" – from white and pink to blue, brown, and beyond – each with unique frequency content. Discover how different noise types sound and why no two noise modules sound exactly the same.
Basic Concept 2: Oscillators & Waveforms
Explore how different oscillator waveforms – like sawtooth, pulse, triangle, and sine – affect the harmonic content and character of a sound.
Basic Concept 1: Pitch and Volume
Discover the core concepts of pitch and volume in this first installment of our Basic Concepts series. Learn how oscillators, frequency, amplitude, and voltage shape the sound in a synthesizer.
