SECTION ELEVEN: PREAMP, ENVELOPE FOLLOWER, RING MODULATOR - 0897. Create metallic sounds using the ring modulator. Connect the outputs of two different VCOs to thering modulator’s inputs. Raise the ring modulator’s slider in the VCA, set the VCA’s gain fullyclosed and use an EG to open and close the VCA. How should the VCOs be tuned to producethe most harmonics and thus the most metallic sounds? CD track 618. Create a patch in which all three VCO’s are tuned in unison, routed to the filter controlled by theADSR EG, and then to the VCA controlled by an EG. Patch any two waveforms from any twooscillators to the ring modulator and raise both sliders fully. Raise the ring modulator’s level inthe filter and/or in the VCA. Notice how this patch will accentuate the high frequencies in thepatch. CD track 629. Patch the ring modulator’s output to the mixer. Patch nothing to the ring modulator (use the VCOoutputs normalled there). Set VCO-1 at a lower frequency; about 100 Hz. Start with VCO-2 aslow as possible while still in the audio range, and sweep its frequency up. Listen for the changein harmonics as VCO-2 continues upwards. CD track 6510. Repeat experiment #9, but this time, use a square wave from VCO-1, and set VCO-1 to LF mode.While conducting this experiment, flip the DC/AUDIO switch. The difference between the twomodes is easily audible in this experiment. CD track 64
090 - SECTION ELEVEN: PREAMP, ENVELOPE FOLLOWER, RING MODULATORREVIEW QUESTIONS FOR SECTION ELEVEN:1. What does the preamplifier do? Why is this simple job so important?2. Explain what happens when the dynamic range of any circuit is exceeded. Is this a good thing or abad thing? When is this effect desirable?3. What aspect of an incoming signal does the envelope follower track? What kinds of signals areusually used with the envelope follower?4. Is the envelope follower’s output always a control signal or always an audio signal?5. What module can the envelope follower replace when external signals are being used?6. How does the ring modulator add harmonics to sounds?7. What kinds of sounds is the ring modulator good at producing?8. Explain the difference between DC and AC coupling on the ring modulator.TERMS TO KNOW:AC CouplingAMAmplifyAmplifierAmplitude ModulationClippingDC CouplingDistortionDynamic RangeEnvelope FollowerFrequency ContentGainHarmonic ContentPreamplifierRangeRing Modulator
