3 Set the modulation depth with the green triangular fader on the right side of each
modulation path.
In the example above, the LFO 1 speed is modulated by channel pressure (aftertouch)
messages of a MIDI keyboard.
You have the option of inserting another modulation source in the middle slot labeled
via. The via modulation source doesn’t directly modulate the destination, but instead it
modulates the source—in essence, modulating the modulator.
When you select a modulator for the via slot, the green triangular fader will divide,
allowing you to set a range for modulation depth. The size of the modulation range
depends on the possible values allowed by the via modulation source.
In the example below, the key number of the MIDI keyboard (Key) determines how
strongly channel pressure controls the Speed of LFO1. Experienced users can read the
picture like this: Pressure to LFO1 Speed via key number.
Inverting Sources
You can also invert the direction of the source’s effect on modulation depth by clicking
the “inv button (right of the word Src or via), depending on which of the sources you
would like to invert.
