Analog Swirl, which is based on the ES2, can generate chorused, swirling analog synthesizer pad sounds.
Volume slider: Set the overall volume level of the instrument.
Modulation slider: Make the sweeping movement of the pad faster or slower.
Cutoff slider: Allow less sound through at low values and more at high values, damping the sound or making it brighter.
Resonance slider: Emphasize the frequency range around the point determined by the Cutoff parameter.
Attack slider: Make the sound start faster or slower. A fast setting makes it sound like striking a piano key, whereas a slow setting makes it sound like bowing a violin string.
Decay slider: Make the harmonic, or bright, portion of the sound sustain for a longer time at slow values. Faster values move to the sustain level more quickly.
Sustain slider: Determine the level of the sound after the Attack or Decay phase has completed.
Release slider: Determine the time it takes for notes to fade out after you let go of the keys on your keyboard.
