Tutorial: Programming a Synth - EGs Controlling Pitch Explained [7/12]

Posted by Catarina Chagas on Sep 9

Welcome to the Synth Tutorial series! If you're new to the world of synthesizers or just getting started with our SkyDust 3D, you're in the right place. In this series, we'll walk you through the fundamentals of sound synthesis using our SkyDust 3D. This article is dedicated to get EGs to control Pitch explained. You can access the last article here Sequencers Explained. If you don't remember what are Envelope Generators, check the article on that topic.

Envelope Generators to Control Pitch

Instead of a static, unchanging pitch throughout a sound, you have the power to use envelope generators to introduce subtle variations. This can be a game-changer for your music. You could start a note an octave below its intended pitch, or perhaps have it glide up or down as it progresses. These techniques can add unique flavors to your music, especially if you're aiming for that "out-of-this-world" synth sound.

Let's take a closer look at how this works in practice. For instance, in our synthesizer, SkyDust, we have an area specifically designed for pitch modulation. Just like you might use LFOs to modulate pitch, envelope generators offer a different approach.

Mastering the Art of Pitch Control

When you dive into pitch control with envelope generators, you'll notice additional parameters beyond the classic attack, decay, sustain, and release. These new knobs allow you to fine-tune your pitch modulation.

Traditionally, when using envelope generators for amplitude control, you start at zero, increase to 100% for the attack, and return to zero for the release. However, when dealing with pitch, you're no longer confined to these norms. You can dictate where your sound begins in pitch space, allowing for intriguing and unconventional starting points.

For instance, you might want your sound to kick off two octaves below its target pitch. This is as simple as setting the envelope generator to -24 semitones, creating a dramatic, attention-grabbing effect. You can adjust the attack time to control how quickly this pitch shift occurs, fine-tuning the impact.

Going Beyond Octaves

The magic of envelope generators controlling pitch doesn't stop at octaves. You can push the boundaries even further. Imagine starting with a pitch that's slightly out of tune, then gradually bringing it into harmony. This can create ethereal, otherworldly effects in your music.

Experimentation is key here. You can introduce pitch modulation to create captivating intros or unique sound effects that set your music apart. Envelope generators can be a powerful tool to breathe life into your compositions.

Mastering EGs to Control Pitch

In some synthesizers, envelope generators can even be applied globally to shape the entire sound or assigned individually to different oscillators. This opens up a world of possibilities where you can blend detuned and precisely tuned elements to craft intricate audio landscapes.

Remember, the beauty of music production lies in experimentation. So, go ahead, play with envelope generators, and explore the limitless soundscapes they can help you create.
