How to Use Any Synthesizer - Lecture by Oscar from Underdog

Introduction

Presenter: Oscar from Underdog
Objective: Teach how to use any synthesizer by understanding common architecture and controls.
Claim: 90% of electronic music gear has a similar architecture.
Agenda:
1. Recap of synthesizer architecture theory.
2. Practical synthesizer workout.
3. Bonus advanced sound design technique.

Main Concept: Subtractive synthesis.
- Start with a large, overwhelming sound and cut away to fit the song.
Basic Architecture:
1. Oscillator: Generates a big sound.
2. Filter: Shapes the sound to be less intense.
3. Amplifier: Controls volume.
Key Components:
- Envelopes: Control the gradual on/off of sound using four parameters:
  - Attack, Decay, Sustain, Release (ADSR).
- LFO (Low Frequency Oscillator): Adds movement by modulating parameters like filter cutoff.

Objective: Familiarize with a new synthesizer's controls.
Checklist:
1. Oscillator:
  - Select octave and waveform.
2. Filter:
  - Adjust cutoff frequency and resonance.
  - Understand envelope impact on filter (envelope amount).
3. Amplifier:
  - Basic ADSR controls.
Additional Controls:
- Effects: Reverb, Delay.
- LFO: Map to filter cutoff and adjust rate.
- Experiment with different notes and playing styles.

Suggested Formulas:
1. Warm, sustained deep bass line.
2. Resonant 303 acid sound.
3. Plucky lead sound.
4. Long sustained atmospheric sound with reverb.

Limited vs Advanced Synths:
- Beginners should start with limited synthesizers to learn controls.
- Use iconic models (e.g., Roland) to learn basic synthesis.
Advanced Synth Features:
- Multiple oscillators for complex sounds (e.g., Super Saw, Hoover).
- Polyphonic capabilities for chords and harmony.
- Complex routing and modulation options.
- FM and Physical Modeling Synthesizers are more advanced topics.

Self-Oscillating Filters:
- Turn resonance high enough to make filter an oscillator.
- Can follow keyboard pitch with adjustments.
- Used creatively in music, exemplified by Jamie xx's work.
