MainStage: 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 dynamically responds 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 first routing column shown above:
The modulation target is Pitch123. The pitch—the Frequency parameter—of Oscillators 1, 2, and 3 is affected 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, vertically drag the upper or lower arrows, or both, 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 off (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).
