254 Chapter 21 ES2
 If Osc Start is set to hard, each initial oscillator phase begins at the highest possible
level in its waveform cycle every time a note is played. This punch is only audible if
the ENV3 Attack Time is set to a minimal value—a very fast attack. This setting is
highly recommended for electronic percussion and hard basses.
Note: Osc Start soft and hard result in a constant output level of the initial oscillator
phase every time the sound is played back. This may be of particular importance when
using the Bounce function of Logic Pro, at close to maximum recording levels.
Surround Range and Diversity
In surround instances, the ES2 extended parameters provide the Surround Range and
Surround Diversity parameters:
 Surround Range: Determines the range of the surround angle. This can be from 0 to
360 °. Put another way, this determines the breadth of the surround field. You can
modulate the movement of sounds—within this surround range—through use of
the Diversity target in the Router (see “Diversity” on page 277).
 Surround Diversity: Determines how the output signal is spread across your surround
speakers. If you choose a value of 0, only the speakers that are closest to the original
signal’s position will carry the signal. A diversity value of 1 distributes an identical
amount of signal to all speakers.
Oscillator Parameters
The following section describes the parameters that you can set individually for each
oscillator. You can find these parameters in the silver area to the right of the ES2
interface.
