Chapter 7: Signal Controllers | EG (ADSR)
⚛ Envelope Generator, sometimes called Transient Generator
⚛ Additional Information
⚛ The following is a transcript of the narration:
✸ Signal Controllers: EG (ADSR)
✸ Envelope Generator (ADSR) controls alteration of the level or timbre over time.
✸ The ADSR has four parameters called Attack, Decay, Sustain and Release.
Patch 4 EG (ADSR)
⚛ The following is a transcript of the narration:
✸ Connect sawtooth wave output to VCF input.
✸ Send Low Pass output to VCA audio input 1.
✸ Open signal in and gain.
✸ Open input / drive level and Cut Off on the VCF.
✸ Set VCO 1 to LFO mode and connect it to Envelope Generator Gate input, to trigger the envelope.
✸ Output of the envelope send to Cut Off CV input.
✸ Adjust LFO rate, time range, Attack, Decay, Sustain and Release knobs.
✸ Set Cut Off CV input on positive (+) and listen how the transient is shaping the Cut Off envelope and that results in change of the tone and dynamics.
Bonus Patch
⚛ The following is a transcript of the narration:
✸ Without changing the previous patch, connect the second output on Envelope Generator (ADSR) to exponential frequency modulation input on VCO2.
✸ Open the level of modulation on the VCO and Cut Off on the VCF.
✸ Play with octave switch and cut off position, and note how strongly timbre and dynamics change.
