Synthesizer Course

Lesson 1 • Understanding Signal Flow

Explains how audio signals travel from oscillator through filters and amplifiers to output. Provides the mental model needed for all subsequent sound design.

Lesson 2 • Basic Sound Concepts for Synthesis

Introduces pitch, timbre, amplitude, and envelope as acoustic properties that synthesis recreates. Links physical sound behavior to synth parameters.

Lesson 3 • Navigating the Synthesizer Interface

Covers panel layout, parameter naming conventions, and preset management. Reduces interface confusion before deeper programming begins.

Lesson 1 • Pulse Width and Waveform Modulation

Teaches manual and automated pulse-width adjustment and its effect on timbre. Prepares students for dynamic waveform changes via modulation.

Lesson 2 • Core Waveform Shapes

Examines sine, triangle, sawtooth, square, and pulse waves and their harmonic content. Directly determines the tonal starting point for any patch.

Lesson 3 • Multiple Oscillator Techniques

Explores detuning, unison, and interval stacking to create richer textures. Builds on single-oscillator knowledge to produce fuller sounds.

Lesson 4 • Oscillator Tuning and Pitch

Covers coarse tuning, fine tuning, and octave transposition controls. Accurate tuning is essential before layering or modulating oscillators.

Lesson 1 • Cutoff Frequency and Resonance

Explains how cutoff sets the frequency boundary and resonance emphasizes harmonics near it. These two controls define the classic synthesizer sound.

Lesson 2 • Filter Types and Topologies

Compares low-pass, high-pass, band-pass, and notch filters and their frequency responses. Choosing the right filter type is the first step in tonal shaping.

Lesson 3 • Keyboard Tracking and Velocity

Configures filter response to follow pitch and playing velocity for natural expressiveness. Prevents thin high notes and muddy low notes in polyphonic patches.

Lesson 4 • Parallel and Serial Filter Routing

Demonstrates routing multiple filters in series or parallel for complex frequency shaping. Expands beyond single-filter designs for advanced tonal control.

Lesson 1 • Velocity and Aftertouch Sensitivity

Routes MIDI velocity and aftertouch to envelope depth and amplitude for dynamic playing. Adds expressive response to keyboard performance.

Lesson 2 • Envelope Shapes for Common Sounds

Maps ADSR settings to real-world instrument behaviors like strings, pianos, and drums. Translates abstract parameters into recognizable sonic results.

Lesson 3 • ADSR Envelope Fundamentals

Defines attack, decay, sustain, and release stages and their effect on amplitude over time. The ADSR is the primary tool for shaping a sound's life cycle.

Lesson 1 • Classic LFO Destinations

Applies LFOs to pitch, filter cutoff, and amplitude to produce vibrato, wah, and tremolo. Demonstrates the most musically useful modulation targets.

Lesson 2 • Low-Frequency Oscillator Basics

Covers LFO waveforms, rate, depth, and phase as tools for cyclic parameter modulation. LFOs are the primary source of rhythmic and expressive movement.

Lesson 3 • Modulation Matrix Architecture

Explains source-destination-amount routing grids found in advanced synthesizers. Unlocks flexible, multi-target modulation beyond fixed routings.

Lesson 4 • Modulation Depth and Scaling

Teaches velocity, key, and aftertouch scaling of modulation depth for expressive control. Prevents modulation from being static and unresponsive to performance.

Lesson 1 • Distortion and Saturation

Applies overdrive, waveshaping, and bit-crushing to add harmonic richness and grit. Transforms clean synth tones into aggressive or lo-fi textures.

Lesson 2 • EQ and Dynamic Processing

Uses equalization and compression to refine frequency balance and dynamic range. Prepares synthesizer sounds for use in a full mix context.

Lesson 3 • Chorus, Flanger, and Phaser

Demonstrates modulation-based effects that thicken, sweep, and animate synthesizer tones. Builds on LFO knowledge by showing effects that use internal modulation.

Lesson 4 • Delay and Echo Techniques

Explains tempo-synced and free-running delay, feedback, and filtering for rhythmic depth. Delay adds movement and space without masking the original signal.

Lesson 1 • Wavetable Synthesis and Scanning

Explains wavetable construction, playback position, and real-time scanning for evolving tones. Wavetable scanning creates movement impossible with static waveforms.

Lesson 2 • Additive Synthesis Basics

Builds sounds by summing individual sine wave partials with independent amplitude envelopes. Provides precise harmonic control unavailable in subtractive synthesis.

Lesson 3 • Hybrid and Layered Synthesis

Combines multiple synthesis methods within one patch for maximum tonal complexity. Requires mastery of all prior synthesis types to execute effectively.

Lesson 4 • FM Synthesis Fundamentals

Introduces carrier and modulator relationships, operator ratios, and modulation index. FM produces metallic, bell, and complex inharmonic timbres efficiently.

Lesson 1 • Patch Organization and Documentation

Establishes naming conventions, tagging, and note-taking practices for patch libraries. Organized libraries accelerate workflow in professional production environments.

Lesson 2 • Designing Lead and Melody Sounds

Creates cutting, expressive lead patches with vibrato, portamento, and filter movement. Leads must cut through a mix while remaining musically responsive.

Lesson 3 • Designing Pads and Atmospheres

Builds slow-attack, evolving pad textures using detuning, modulation, and reverb. Pads require careful balance of movement and harmonic density.

Lesson 4 • Analyzing Target Sounds

Trains the ear to identify frequency content, envelope shape, and modulation in reference sounds. Accurate analysis is the prerequisite for accurate recreation.

Lesson 5 • Designing Bass Sounds

Builds sub bass, mid bass, and distorted bass patches using targeted synthesis choices. Applies oscillator, filter, and envelope skills to a foundational mix element.
