The noise generator provides a further sound source that can be used alongside the two oscillators.
Important: The noise generator in the oscillator section is independent of the noise generator in the U/V detection area. For further information about voiced and unvoiced signals, see EVOC 20 PolySynth (U/V) detection parameters.
Level knob: Control the amount of noise added to the signals of the two oscillators.
Color knob: Set the timbre of the noise signal. Turn full-left to hear white noise. Turn full-right to hear blue noise (high-passed noise). White noise has traditionally been used to create wind and rain sound effects. It has the same energy in each frequency interval. Blue noise sounds brighter, because its bass portion is suppressed by a highpass filter.
Tip: Set Color to the full-right position and Level to a very low value to achieve a lively and fresh synthesis signal.
