![]() Now it is possible to have a huge range of filter types, all with unique quirks and characteristics.įilters have two important controls – cutoff frequency and resonance. These are just like the filters you find in your DAW or on a parametric EQ except fine-tuned for synthesis, often emulating circuits in vintage synths.įor many early analog synths, lowpass filters were the only option. FiltersĪfter the sound is generated by the oscillators, it is processed with filters to shape the timbre. On PG8X, DCO = oscillator and VCF = filter, terminology used on the Roland JX8P which it is based on. Classic analog synths were almost always subtractive, meaning many subtractive soft synths are presented as emulations of vintage hardware. This is not exclusive to subtractive synthesis and we’ll talk about this more at the end. We of course use modulation sources such as LFOs, envelopes and velocity to affect the oscillators and filters to shape our sounds. A lot of sounds can be made with just a single oscillator, but combining two or more oscillators will create much richer sounds. Often the oscillator sounds you start with are simple shapes like saw waves, square waves or even white noise. The idea behind subtractive synthesis is you start with a sound that is rich in harmonics, then you use filters to remove frequencies in a more selective manner. This is the best one to start with as the concept is quite basic and it’s responsible for a lot of classic synth sounds. If you want to get your head around sound design, Syntorial is an excellent platform to learn synthesis on (read our review). We’ll look at these terms and explore where they come from and what they mean for producers and sound designers. Having said that, your synth will still lean into one style more than the others. Most modern synths incorporate a few styles so it’s important to get a feel for the most common approaches. The truth is, it’s hard to describe how a whole method of synthesis works with just a simple label. The most common ones have confusing names like wavetable, FM, additive and subtractive synthesis. In the world of synthesis, there are a wide range of approaches we can take when it comes to generating sounds from scratch.
