Chapter 9. Subtractor -- Close Up - Pg. 198

This is a fantastic effect that can be best explained by example: 1. 2. 3. 4. 5. Initialize the Subtractor patch. Select the Sine Wave for Osc 1. Activate Osc 2 and select the Triangle Wave for Osc 2. Turn the FM knob to 50 and start playing some notes on your keyboard to hear the FM effect. Turn the Osc Mix all the way to the left so you can just hear Osc 1. Change the semitone settings on Osc 2 and notice that you can still hear the FM effect, even though you are listening to just Osc 1. As Osc 2 is a modulator when using FM, its modulation effect is still heard, even though the actual output of the oscillator is inaudible. Because the Noise Generator is routed through the output of Osc 2, it can also be used to modulate Osc 1 through FM. Try the following example. Make sure that you are playing a sequence of some kind to hear the effect: 1. 2. 3. 4. 5. Turn off Osc 2 and turn on the Noise Generator. Turn the Osc Mix completely to the right so you will just hear the Noise Generator. Play a sequence. Set the Level knob of the Noise Generator to 64. Set the FM knob to 24.
