Introduction

  • What is the Analog Model?
    • Based on modular synthesis techniques.
    • Focuses on subtractive synthesis.
    • Built off of four primary tools:
      • Oscillators
      • Filters
      • Level Controls
      • Modulators


  • Why is this Important?
    • It is the basis for most modular synth techniques.
    • It is also the basis for a lot of synth-based music.
    • It provides a useful way to do sound design iteratively.
    • It sounds good, too!


  • What is necessary for this workshop?
    • A laptop with audio capability.
    • A pair of headphones.

Oscillators and Tone Generation

  • Oscillators are the way that synths make sound. They create repeated waveshapes at a set frequency.
    • Select an Oscillator from the contextual menu (ctrl/right-click, then Paste From | BEAP | Oscillators | Oscillator).
    • An oscillator by itself creates waveforms, but is not routed to our computer's output. For this, we need an Output Module.
    • Select a stereo output from the contextual menu: Paste From | BEAP | Output | Stereo
    • Connect the output of the oscillator to both inputs of the Stereo module.
    • Turn on the DSP (this might need explaining), and you should hear a tone.
  • The two most important setting of the oscillator are the tuning and the waveshape.
    • Change the tuning by adjusting the offset knob on the front of the Oscillator module.
    • Change the waveform by selecting a waveform image in the button matrix.
    • Note how the waveform changes the timbre, but not the pitch, of the oscillator.
  • More than one oscillator can be used at a time to create more interesting tonality.
    • Select another Oscillator from the menu, or copy the existing one by option/alt-dragging the one already on-screen.
    • Select the patchcord going to the right inlet of the Stereo module, then grab the top handle and drag it from the first to the second oscillator.
    • Now you will hear an oscillator in each ear of your headphones. Adjust the offset and waveform in each to verify the changes.
