Noise Generator The Noise Generator can be thought of as another oscillator. But this oscillator does not generate a pitched waveform. Rather, it generates noise that can be used for several sound design and instrumental possibilities, such as "wind noises" and percussion sounds. To activate the Noise Generator, click the power button located in the upper-left corner of its interface. Let's have a look at the main parameters of the Noise Generator: Noise Decay--This parameter determines the length of time the noise will last when a note is played. Unlike Osc 1 and 2, the Amp Envelope does not govern the Noise Generator's parameters, so you can create a short burst of noise at the beginning of a sound using just this parameter. Noise Color--This parameter controls the character of the noise. The easiest way to think of it is like a single band of EQ. If you turn the knob to the right, the noise becomes brighter. If you turn the knob to the left, the noise becomes muddier sounding and bass heavy. Level--This parameter controls the volume of the Noise Generator. Let's try an example of the Noise Generator. 1. 2. 3. Choose Initialize Patch from the Edit pull-down menu to reset the Subtractor. Note that Osc 2 should be turned off. Activate the Noise Generator by clicking on its power button. Play a note on your MIDI keyboard to hear the mix between Osc 1 and the Noise
