Modulation routing in ES1 and ES2
ES1 and ES2 provide an easy way to route a control—a modulation source—to part of the sound
engine—a modulation target.
ES1 modulation routing
You create an ES1 modulation routing by selecting a modulation target in the left or right
column of buttons in the Router section.
•
You use the left column to set a modulation target that can be controlled, in amount, with the
modulation wheel of your keyboard.
•
The target you select in the right column will dynamically respond to keyboard velocity.
•
The amount, or range, of this modulation is determined by the two arrows shown in the
sliders, Int via Whl and Int via Vel. The upper arrow determines the maximum amount of
modulation, and the lower arrow determines the minimum amount of modulation.
ES2 modulation routing
ES2 provides ten modulation routings, in columns. Each routing column is quite similar to the
modulation controls found in ES1.
In the rst routing column shown above:
•
The modulation target is Pitch123. The pitch—the Frequency parameter—of Oscillators 1, 2,
and 3 is aected by LFO2, the modulation source.
•
LFO2 is the modulation source. The two arrows to the right of the column indicate the
modulation amount. To make the modulation more intense, drag the upper and/or lower
arrows up or down, thereby increasing the range of the modulation amount. The upper
arrow determines the maximum amount of modulation, and the lower arrow determines the
minimum amount of modulation.
•
The via control is the ModWhl. Its range is determined by the sliders to the right of the
channel. The amount of modulation is directly controlled with the modulation wheel of your
keyboard. When the modulation wheel is at the minimum setting, at the bottom of its travel,
the amount of oscillator pitch modulation is minimal, or o (no modulation). As you move the
modulation wheel upward, the frequency of all three oscillators is directly controlled by the
LFO (within the range determined by the sliders).
