Forget preset browsing. This program teaches you to create any sound you can imagine by understanding synthesis at the signal level. You'll learn what's actually happening when you turn knobs, not just which settings make things sound good.

Signal flow and oscillators

Everything starts with oscillators generating simple waveforms: sine, saw, square, triangle. Understanding how harmonic content differs between these waveforms explains why certain starting points work better for specific sounds. A sawtooth contains all harmonics, making it perfect for filtered basses. Sine waves have none, ideal for FM synthesis carrier oscillators.

We use both hardware synthesizers (when available) and software like Serum, Vital, and Operator to demonstrate identical concepts across different implementations. The goal is understanding synthesis itself, not any particular instrument.

Filters and envelope generators

Subtractive synthesis shapes sound by removing frequency content. Learning filter types—lowpass, highpass, bandpass, notch—and their resonance characteristics gives you precise control over timbre. You'll analyze commercial sounds spectrally, then recreate them using only filters and envelopes to develop your ear.

Envelope generators control how parameters change over time. ADSR envelopes seem simple until you're shaping transients on percussion or creating evolving pad movements. We spend significant time on envelope design because it separates amateur sounds from professional ones.

Synthesis is problem-solving. You hear a sound in your head, break it into components—pitch, timbre, envelope, modulation—then build each piece systematically until it matches your vision.

Modulation and FM synthesis

Later modules cover LFO modulation, frequency modulation synthesis, and wavetable scanning. FM creates complex harmonic relationships impossible with subtractive techniques. Understanding operator ratios and modulation indices opens up metallic bells, electric pianos, and aggressive bass sounds.

Practical application

Each week includes sound design challenges: recreate this bass, design five unique kick drums, or build an evolving ambient texture. You'll submit your patches for review, receiving feedback on signal flow efficiency and creative decisions.
