Wavetable synthesis is an interesting method of synthesis, it does not use oscillators to generate its sound. Instead it has single cycle samples of prerecorded sounds at each position on the wavetable, and as you change positions, it reproduces whichever wave is at that point in the table.
Examples of Wavetable SynthesizersEdit
Native Instruments Massive
Concrete FX Kubik
Synthblitz Audio Nitroflex
