Try this exercise to see how ring modulation works: 1. 2. 3. 4. 5. 6. 7. Initialize the Subtractor patch before you begin. Activate the ring modulator.

At this point, the ring modulator should sound like it is playing one octave above Osc 1. Turn the Osc Mix knob clockwise to the right to hear just the ring modulator. Play some notes on your MIDI keyboard or play a sequence of notes in the Reason sequencer. Make a few adjustments to the semitone controls of either Osc 1 or 2 to start hearing the dissonant effect created by the ring modulator. At this point, you can now turn the Osc Mix knob to the left in order to bring Osc 1 back into the mix.
