What Are Synthesizers? (The 4 Basic Building Blocks of Synths)

 

Additive Synthesizers

The first additive synths were made in the early 1900s, making them the earliest synths to hit the scene. When synths were all analog, additive was most famous for powering electric organs.

Additive was the secret recipe behind famous keyboards like the Hammond Organ.

Additive synthesis is all about combining different sounds to make a new one.

Think of it as a painting. To make a detailed portrait, the painter works in stages.

First, she’ll throw down some basic colors to create the background. In the second coat, she’ll add in the general outline of the person she’s painting.

Then she starts getting more precise. She’ll meticulously add in layer after layer of brushstrokes.

On their own, these layers all look pretty simple. But when you stand back and look at the full picture, you see a super realistic image of a person.

Additive synthesis uses the same idea. You layer a bunch of simple sound waves to create a sound that’s way more complex.

The only difference is instead of adding new coats of paint, you’re adding more frequencies.

Additive synths usually have multiple sine wave oscillators. Sine waves are the simplest type of sound out there.

Most sounds are made up of a bunch of different frequencies.

When you pluck a guitar string, you’re not just hearing one note. There are tons of higher, quieter frequencies layered on top of it.

These higher frequencies, called harmonics, shape the tone of the sound. It’s these harmonics that decide whether an instrument sounds warm or cold, round or sharp, and so on.

But a sine wave is just one single frequency.

They might use the simplest sound possible. But by layering sine waves on top of each other you can make some really wild sounds with additive synths.

By combining sine waves at different frequencies, you can make all kinds of new sounds.

 

Additive in Action

But enough theory. Let’s see for ourselves how additive actually works. Here’s Logic Pro’s Alchemy synth with just one oscillator on.

sine wave oscillator

The oscillator is making a sine wave, which sounds like this:

If I add two more sine waves, I can make a totally new sound.

I’ll set one of the new sine waves to be an octave higher than the first. The other will be two octaves higher.

multiple sine wave oscillators

By turning down the volume on these new sine waves, I can blend them in so they sound like harmonics on top of the lower one.

Now our synth sounds way sharper than the lone sine wave we heard before.

And that’s just three sine waves! Additive synths usually have tons of oscillators, giving you plenty of tonal options.

Additive synths allow you lots of control over the sound you’re creating.

You’re literally handpicking which frequencies to include, so it’s easy to hone in on a sound you like.

You can do some ridiculously advanced stuff with additive synths.

 

Getting Creative with Additive Synthesis

Nowadays, most synths aren’t just additive or subtractive. Most synths combine ideas from either additive or subtractive with another type of synthesis.

A lot of sample-based synths let you use additive synthesis to totally change how the sample sounds.

For example, I can load a sample into Logic’s Alchemy synth and tell it to reconstruct the sample using additive synthesis.

This means Alchemy will automatically recreate the sample using sine waves. This is called “resynthesis.” The result is a more digitized version of the original sample.

There’s plenty of room for interesting sound design!

 

Conclusion

Even though it was the first type of synth, additive is far from a thing of the past. There are plenty of new, exciting additive synths being made today.
