- What is the Analog Model?
- Based on modular synthesis techniques.
- Focuses on subtractive synthesis.
- Built off of four primary tools:
- Level Controls
- 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.
- In order to have the two oscillators "mix" together, we need to use another device to combine them.
- Add an audio mixer using the Paste From | BEAP | Mixers | Audio option from the contextual menu.
- Connect the two oscillators to inputs 1 and 2 of the mixer, then connect the output of the mixer to the two Stereo inputs.
- Turn up the volume of the mixer channels to hear a mix of the tones. You can alter the volume of each oscillator to create a nicely blended tone.
- At this point, we are able to hear the oscillators, but it would be nice to change the pitch in a musical way.
- We need a controller, and will create a virtual keyboard using Paste From | BEAP | Input | Keyboard
- Connect the CV output to the 1V/Oct inputs of the oscillators. The terminology used here is from the modular synthesis world...
- Lock the patch and click on the keyboard keys. You should hear the pitch change to match the keyboard notes.
