Sound Design and Synthesis Techniques

Sound design is the heart and soul of Synthwave music. This chapter will explore various sound design and synthesis techniques essential for crafting the lush, nostalgic sounds characteristic of The Midnight and the Synthwave genre as a whole. Whether you’re using hardware synthesizers or software VSTs, these methods will help you create rich and immersive sonic landscapes.

1. Oscillator Basics

At the core of any synthesizer lies its oscillators, which are responsible for generating sound waves. Understanding different waveforms is crucial:

  • Sine Waves: Smooth and pure, often used for sub-bass sounds.
  • Sawtooth Waves: Bright and rich, great for leads and strong harmonics.
  • Square Waves: Create a hollow, woody quality, often used in retro synth sounds and arpeggios.
  • Pulse Waves: Similar to square waves but with varying pulse width, adding character and richness to leads.

Tip: Layer Oscillators

  • Combine different waveforms to create warmth and complexity in your sound. For example, pairing a sawtooth wave with a square wave can add depth to your lead sound.

2. Using Filters Effectively

Filters shape your sound by cutting or boosting specific frequencies:

  • Low-Pass Filter (LPF): Removes higher frequencies, creating a warmer tone—excellent for pads and bass sounds.
  • High-Pass Filter (HPF): Cuts off lower frequencies, useful for cleaning up sounds and maintaining clarity.
  • Band-Pass Filter: Isolates a specific frequency range, often used for creating distinct, resonant sounds.

Tip: Filter Resonance

  • Adding resonance to your filters creates a pronounced peak at the cutoff frequency, providing a more aggressive sound for leads and basslines.

3. Modulation Techniques

Modulation parameters can breathe life into static sounds, making them more dynamic and expressive:

  • LFO (Low-Frequency Oscillator): Use LFO to modulate parameters like pitch, filter cutoff, and amplitude, creating movement in your sounds. A slow LFO on filter cutoff can introduce interesting tonal shifts.
  • Envelopes: Envelopes control how a sound evolves over time. Use an ADSR (Attack, Decay, Sustain, Release) envelope to shape the attack and sustain of your sounds, achieving anything from sharp plucks to smooth pads.

Tip: Experiment with Envelope Shapes

  • Changing the attack or release time can drastically alter the feel of a sound. Longer attack times can produce softer swells, while shorter ones can create immediate impacts.

4. Creating Lush Pads

Pads are essential in setting the atmospheric backdrop in Synthwave tracks:

  • Layering: Start with two or three oscillators. Use a mix of sawtooth and square waves, detuning them slightly to create a fuller sound.
  • Reverb and Chorus: Apply a generous amount of reverb and chorus effects to give the pad a sense of space and depth.
  • Take Advantage of Slow Modulation: Use a slow LFO to gently modulate the filter cutoff, adding a sense of movement to the pad.

5. Crafting Melodic Leads

Leads are often the most prominent sound in a Synthwave track:

  • Choose Your Oscillator Configuration: Use a sawtooth wave and add one or two square waves tuned an octave higher for a rich, broad lead sound.
  • Add Portamento/Glide: Enable glide to create smooth transitions between notes, giving your lead a more expressive character typical of Synthwave.
  • Apply Reverb and Delay: Use these effects carefully to make your lead stand out while keeping it coherent in the mix. Experiment with different delay times to create rhythmic interest.

6. Punchy Bass Sounds

A strong bassline drives Synthwave tracks:

  • Use Subtractive Synthesis: Start with a sawtooth or square wave and apply a low-pass filter to remove the higher frequencies, making the bass sound fuller and deeper.
  • Drive It with Distortion: A touch of distortion can add grit and make your bass more aggressive. Use it sparingly to enhance rather than overpower the sound.
  • Sidechain Compression: Use sidechain compression triggered by the kick drum to create a pumping effect, ensuring your bass remains present without muddying the mix.

7. Incorporating Samples and Effects

Don’t be afraid to incorporate samples to enhance your sound design:

  • Vocal Samples: Add processed vocal chops to your leads or pads for a unique character.
  • Ambient Effects: Use atmospheric sound effects like pads, risers, and impacts to create tension and resolution within your tracks.

Conclusion

Mastering sound design and synthesis techniques is crucial for creating captivating Synthwave music. By experimenting with oscillators, filters, modulation, and layering, you can develop rich, emotive sounds that define the genre. Embrace your creativity as you create sonic landscapes that transport your audience to vibrant, nostalgic worlds.
