Getting To Know Wavetables
Why Do You Need To Master Them?
Getting to Know the Basics of Wavetables in Serum
- On the top of the editor, the FFT section allows you to build harmonic and relative phases of waveforms.
- Right below it, there is a Menu Bar that includes different functions that are used to edit wavetables.
- On the editor interface, you will see a middle section called Big Wave Display. This is where you will see the wavetable materialize.
- On the left side of the editor, there is a Draw Tools tab that lets you build the waveforms manually.
- There is a formula bar at the bottom left corner called Formula Parser, where you can enter specific math functions for generating wavetables.
- Whereas the Sub Table Thumbnails section is used to reorder and organize the subtables.
How to Create Wavetables in Serum
1. Create Wavetable by Importing a Sample
- If you have a sample in your sound library or on your computer, you can easily drag and drop it on any one of the oscillators.
- When you import the samples, you can manually adjust the pitch, frame size, or FFT.
- Once you drop the sample and hold the mouse button to choose the pitch of your choice on Serum.
- There are four FFT options for the wavetables i.e., 256, 512, 1024 & 2048. When you have vocal and drum samples, you will choose the highest FFT if the sample duration is longer.
2. Creating Wavetable of Samples with More Features
- Import any sound sample of your choice into the Serum wavetable editor, for instance, an 808 sub bass.
- Once sample is loaded on the OSC A, again hover the mouse over import settings and use the option of 'Pitch Avg' in the constant frame size if your sample has a consistent pitch. This resynthesizes the sample in individual frames, which allows you to tweak it more easily.
- You will find a pencil icon on the OSC A disk to launch the wavetable editor.
- This will lead to the formation of a wavetable in the display. Whereas, on the sub-table section, you will observe that the sample is divided into various frames. It can be up to 256 frames at a time. However, not every sound sample will have 256 frames since it depends on the sample duration.
- Initially, the divided frames will seem rough and jagged. To smooth that out you can use two methods. Either you can use the Morph option or use ‘Fade Edges’ found in the Process tab of the menu bar command to make the frame transition smooth.
- In order to experiment with sound by adjusting the modulators, different parameters such as LFO shapes and sound effects to incorporate distortion or warping.
- You can edit the wavetable to your liking by syncing or leveling the frames with the 'Normalize' feature and by adjusting the WT POS knob to bring movement in the sample.
- You can also remove any flat frames that are usually found at the beginning and end of your wavetables. Save the wavetable by clicking on the disk icon.
3. Creating Wavetable in Serum Via an Image
- Firstly, find a PNG format image, which you can convert into a wavetable and crop it in a square. Why so? Because many experts find that Serum converts the square image with better results.
- Import the image into OSC A's window by simple drag and drop method. Once you do that, Serum will convert the image into frames.
- Remember that Serum transforms the visual cues into a sonic wavetable through color perception. A darker image will be busy, whereas a light image may come out mellow and spaced out.
- Once you have the wavetable in frames, you can tweak and edit the empty spaces by manually removing them or through the Morph effect to fade it out.
