This control is unique to the SYNTH Oscillator in Omnisphere. Moving this slider sweeps through the waveforms on the selected wavetable, and depending on the wavetable, can create subtle or dramatic changes. The waveform display will dynamically change the waveshape as the SHAPE slider is moved. The SHAPE slider is modulatable.
NOISE waveform only – SHAPE becomes a complex filter control, which varies from white noise (all frequencies) at the minimum setting, to pink noise (reduced high frequencies) at the maximum setting.
