Chapter 21 ES2 251

Global Parameters

These parameters impact on the overall instrument sound produced by the ES2. You

can find the global parameters to the left of the oscillators, and above the filter section.

In surround instances, two additional global parameters are shown in the Extended

Parameters section.

Tune

Tune sets the pitch of the ES2 in cents. 100 cents equals a semitone step. At a value of 0

c (zero cents), a' is tuned to 440 Hz or concert pitch.

Analog

Analog alters the pitch of each note, plus the cutoff frequency in a random fashion.

Much like polyphonic analog synthesizers, all three oscillators used by each synthesizer

voice maintain their specific deviation, but are shifted by the same amount randomly.

Medium values simulate the tuning instabilities of analog synthesizer circuitry which

can be useful in achieving that much sought after warmth of the ES2’s analog

hardware counterparts.

If the ES2 is set to mono or legato, Analog is only effective with Unison activated. In this

situation, Analog sets the amount of detuning between the stacked (unison) voices.

If voices is set to 1 and Unison is not activated, the Analog parameter has no effect.

Read more on these parameters in “Keyboard Mode (Poly/Mono/Legato)” on page 252.

CBD

Fine Tuning detunes Oscillators 1, 2, and 3 in cents (1/100th percentages of a semitone).

The detuning results in beats (phasing), the speed of which is determined by the

difference between the two oscillator frequencies (given that these frequencies are

nearly identical). The higher the pitch, the faster the phasing beats are. High notes may

therefore seem to be further out of tune than lower notes.
