Chapter 3 ES2 42
ES2 emulation of detuned analog oscillators
The Analog parameter randomly alters the pitch of each note and the lter cuto 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 signicant pitch instability, which can sound truly out of tune—
but this may be perfect for your needs.
Rotate the Analog knob to randomly alter the pitch of each note, and the lter cuto frequency.
Much like polyphonic analog synthesizers, all three oscillators maintain their specic 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 eective 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 eect. For more information about these parameters, see Set the ES2 keyboard
mode on page 47.
