When the oscillator in in Synth Mode, Omnisphere uses DSP wavetables generated in real-time by the STEAM engine. A wavetable is a collection of single-cycle waveforms that can be swept through smoothly (using the SHAPE slider), creating dynamic timbral changes. These changes can be subtle or dramatic, depending on the timbral variety of the waveforms in a wavetable.
Omnisphere has over 400 available wavetables, ranging from classic vintage synthesizer waveforms to aggressive, digital waveshapes. SYNTH mode’s Waveform Display features a graphic representation of the waveshape. Changes that are made to the three unidirectional sliders in the MAIN section below will dynamically and visually alter the contour of the waveform.
