7 The basics of subtractive synthesis
Subtractive synthesis appeared at the end of the 1960’s, giving birth to the first analog synthesizers:
Moog, ARP, EMS, Oberheim, Roland (SH or Jupiter series), Yamaha (CS series) and Korg (MS and PS
series). During the 1980’s, the purely analog additive synthesis model of the first keyboards was
progressively superseded by wave table oscillators (JUPITER-8VS) and sample based instruments.
7.1 The basics
Of all forms of audio synthesis, subtractive is one of the oldest, and to this day, the most frequently
employed by sound designers and musicians alike. This is due to the simplicity with which complex
sounds can be created, over the more unwieldy forms of synthesis techniques, many of which
employ elements of subtractive synthesis, such as lowpass filtering. As a basic overview to
subtractive synthesis, one may consider any sound created either in nature or on your synthesizer of
choice, as consisting of a number of sine waves, or harmonics grouped together. In subtractive
synthesis, we start with a harmonically rich sound such as a saw wave, and through filtering, we
remove the sine waves (or harmonics) that we do not want. This as you can imagine is much more
complex than turning a filter control knob!
7.1.1 The main elements
7.1.1.1 The Oscillator or VCO
The oscillator or VCO (Voltage Controlled Oscillator) is the starting module (with the noise module
which is often classed among the oscillators) for the creation of a sound on an analog system.
It will generate the initial sound signal. We can think of the oscillator like a violin string that once
stroked or plucked, vibrates to create its sound.
