EVOC 20 PS noise generator in Logic Pro for iPad
The EVOC 20 PS Synthesizer section noise generator provides a further sound source that can be used alongside the two oscillators.
Important: The noise generator in the Synthesizer section is independent of the noise generator found in the Output parameters. For further information about use of the Output section noise generator for voiced and unvoiced signals, see EVOC 20 PS (U/V) detection.
Noise generator parameters
Noise Volume knob and field: Control the amount of noise added to the signals of the two oscillators.
Noise Color slider and field: Set the timbre of the noise signal. Slide to the full-left position to hear white noise. Slide 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 Noise Color to the full-right position and Noise Volume to a very low value to achieve a lively and fresh synthesis signal.
