This is similar to wavetables, which have many tiny “snapshots” of audio. These images are pretty small – often less than 100 x 100 pixels. You can think of sprite sheets in 2D video games, where animated sequences are stored as a series of images in frames. The way wavetable oscillators work is comparable to animation. (After some good free synths? Check out our list of the best free VST synths on the net!) “Animated Oscillators” Plus there’s an ever-expanding library of wavetables available on the internet (don’t forget to download the ones at the end of this article!). But the focus was more on processing the included wavetables with the onboard analog filters rather than browsing a library of user-generated wavetables.įast-forward to the modern era, where even low spec laptops can run powerful synthesizers and manipulate wavetables on the fly. Not to imply Waldorf’s wavetable synths were rubbish – they are still highly regarded and capable of many interesting sounds. Users only had limited options for creating their own wavetables, and the quality was nowhere near as good as modern VSTs like Serum. The Waldorf Microwave XT is a funky looking wavetable synth from 1998. Wavetable synthesis was pioneered by Wolfgang Palm of PPG fame in the late 1970s, and this style was adopted by Waldorf in the 80s and 90s for their Wave and Microwave synths. Though wavetable synths have existed since the dawn of digital synthesis, they were computationally expensive and primitive until only recently. Many great Serum patches don’t even modulate the wavetable position! We were fine with this, and still to this day plenty of useful synth sounds can be made with these simple shapes. A Brief History About Wavetable Synthesisįor a long time, plain shapes such as squares, saws, triangles, and sine waves built the majority of our synth sounds, and we were used to having just one shape per oscillator. You decide how quickly it plays back the frames and in what order. You can also think of a wavetable as being a “frozen sound”, with no fixed duration, pitch, start, or end. We can also have up to 255 other waves in the same set (at least for most synths). Inside each frame, we can have any wave we want. Thanks to wavetables, our oscillators are no longer limited to just simple shapes or “static tones”. But inside an oscillator, this tiny sound is – of course – looped to make a tone. If you played a single frame from a wavetable just once, it would sound like a click. These frames are very small, usually 2048 samples long which is less than 50ms of audio at 44.1kHz. Just by looking at Serum, you get a pretty good idea of what wavetables are and how they work! WT POS selects a frame for the oscillator to play (highlighted in yellow). This “animates” the oscillator, allowing you to create a huge range of morphing tones inside a single oscillator. This parameter is often modulated by the usual sources – LFOs, envelopes, velocity, key position etc. These frames are selected with a “position” parameter (WT Pos in Serum) and this changes the tone being produced by the oscillator. Wavetables are made three-dimensional by storing many different 2D shapes in a series of frames. Simply put, a wavetable is a 3D oscillator shape, as opposed to traditional 2D shapes like square and saw waves. Powerful synths like Serum feature a whole suite of tools to help you create custom wavetables with ease, as well as extra shaping options that are done “on the fly” to further expand the tonal possibilities.īut really, to get a good grasp on wavetable synthesis, we need to dive deeper and get to know all about wavetables. Wavetable synths almost always have filters and built-in effects. (If you need to brush up on the most common synthesis methods, check out our article Wavetable vs FM vs Additive vs Subtractive Synthesis.) Wavetables are “complex” oscillator shapes essentially pre-defined sets of tiny wave shapes that go far beyond traditional shapes like triangle and saw waves – although these are perfectly fine, too! Wavetable synthesis is a method of synthesis where oscillators create sound “frame-by-frame” using wavetables. But it’s always useful to learn how wavetable synthesis works, and why it has come to dominate in such a huge way. It’s certainly fun and easy to play around with presets in your tracks with little regard for the technology. While they each incorporate many different types of synthesis, at their core are powerful wavetable oscillators capable of generating a huge range of complex, animated sounds inside a single oscillator. Xfer Serum, Arturia Pigments, Reveal Sound Spire, and NI’s Massive X are some of the most popular workhorse synths, all of which use wavetables. Wavetable synths are dominating the market when it comes to powerful, “do-everything” VST synthesizers.
