Chapter 1: Foundations of Synth Sound

What Is Sound Design?

Sound design means shaping sound on a synth instead of just using presets.

You control:

  • Pitch
  • Tone (timbre)
  • Loudness
  • Movement over time

With these, you build everything from basses to pads and FX.

> Goal: Hear a sound in your head, then build it on purpose.

The Signal Flow Map

Most synths follow this path:

1. Oscillator – raw sound

2. Filter – shapes brightness

3. Amplifier (Amp) – controls loudness

4. Modulation – makes things move

If a sound is wrong, trace this chain.

Rule: Fix problems earlier in the chain first.

Types of Synths

Common synth engines:

  • Subtractive: starts bright, then filters; great for most classic sounds
  • FM: uses one waveform to modulate another; metallic, sharp
  • Wavetable: scans through many wave shapes; versatile, modern

We’ll focus on subtractive, because its ideas transfer to the others.

Monophonic vs Polyphonic

  • Monophonic (mono): plays one note at a time
  • Great for basses, leads
  • Polyphonic (poly): plays chords
  • Great for pads, keys

Same engine, different feel.

Tip: For a strong lead, start with mono and add a bit of glide.
