Chapter 21 ES2 271
Sine Level
The Sine Level knob (located next to the Filter 2 section) allows the mixing of a sine
wave (at the frequency of Oscillator 1) directly into the dynamic stage, independent of
the filters. Even if you have filtered away the basic partial tone of Oscillator 1 with a
highpass filter, you can reconstitute it through use of this parameter. Please note:
 In cases where Oscillator 1 is frequency modulated by Oscillator 2 (if you have turned
up FM with the waveform selector), only the pure sine wave is mixed into the
dynamic section, not the distorted FM waveform.
 Low frequency modulations of Oscillator 1’s pitch, set in the Router, affect the sine
wave frequency mixed in here.
Note: Sine Level is well suited for adding warmth and a fat bass quality to the sound.
Thin sounds can be fattened up with this function, given that Oscillator 1 actually plays
the basic pitch.
The Router
The ES2 features a modulation matrix, called the Router. If the vector envelope is
displayed, click the Router button to view the Router.
Any modulation source can be connected to any modulation target—much like an old-
fashioned telephone exchange or a studio patchbay. The modulation intensity—how
strongly the target is influenced by the source—is set with the associated vertical slider.
Note: To set the modulation intensity to zero, just click on the little zero symbol (the
small circle) right beside via.
The intensity of the modulation can also be modulated: The via parameter determines
yet another modulation source, which defines the amount or intensity of the
modulation.
