The Beginner's Guide to Synths for Music Production

Introduction

• Synthesizers have significantly evolved since the late 19th century.
• Bob Moog's Minimoog in 1970 made synths widely available.
• Synths are integral to both mainstream and underground music today.
• This guide covers the basics of how synths create sound and tips for synthesis.
• Relevant to both hardware and software synthesizers.

What is a Synthesizer?

• Synths mimic the process of creating sound through vibrations.
• Instead of natural vibrations (like a guitar string), synths use electrical signals.
• Basic components of synths:
  • Oscillators: Produce and shape sound through parameters known as patches.

Oscillators

• Oscillators (VCOs) create the fundamental sound for synths.
• Main controls:
  • Frequency: Waveform cycle speed (Hz), perceived as pitch.
  • Amplitude: Volume of the sound, measured in dB.
  • Waveshape: Determines the sound's character; main shapes include sine, sawtooth, square, and triangle.
• Synths often have multiple oscillators for unique sound creation.
• Low Frequency Oscillators (LFO) modulate synth parameters without affecting tone.

Filters

• Filters (VCFs) shape the sound's harmonic qualities, known as timbre.
• Common filter types:
  • Low-pass: Allows frequencies below a set point; used for warm sounds.
  • High-pass: Allows frequencies above a set point; emphasizes highs.
  • Bandpass: Allows a selected group of frequencies; used for vocal emulations.
  • Notch: Removes specific frequencies; creative uses.
• Resonance boosts frequencies around a cutoff point, useful for filter sweeps.

Amplifiers and Envelopes

• Amplifiers (VCAs) control volume.
• Envelopes determine how sound evolves over time using ADSR stages:
  • Attack: Time to reach maximum volume.
  • Decay: Duration at maximum level.
  • Sustain: Volume level during decay.
  • Release: Time to silence after a key is released.

Modulation

• Modulation involves dynamic changes in synth parameters.
• Envelopes modulate almost every parameter.
• LFOs can also modulate parameters like panning and pitch.

Conclusion

• Synths offer vast potential for sound creation.
• Understanding and experimenting with synth parameters is crucial.
• Continuous learning and experimentation enhance synthesis skills.
• Resources: Manuals, YouTube tutorials, synth experts.
