The Analog parameter randomly alters the pitch of each note and the filter cutoff frequency.
Low Analog values can add a subtle richness to the sound.
Medium Analog values simulate the tuning instabilities of analog synthesizer circuitry, which can be useful in achieving that much sought-after “warmth” of analog hardware synthesizers.
High Analog values result in significant pitch instability, which can sound truly out of tune—but this may be perfect for your needs.
Rotate to randomly alter the pitch of each note and the filter cutoff frequency.
Much like polyphonic analog synthesizers, all three oscillators maintain their specific frequency deviation from each other, but the pitches of all three oscillators are randomly detuned by the same Analog amount. For example, if the Analog detuning is set to around 20%, all three oscillators (if used) randomly drifts by 20%.
Note: If ES2 is set to Mono or Legato keyboard mode, the Analog parameter is effective only when Unison is turned on. In this situation, Analog sets the amount of detuning between the stacked (unison) voices. If the Voices parameter is set to 1 and/or Unison is not active, the Analog parameter has no effect. For more information about these parameters, see Set the ES2 keyboard mode.
