Modulation in Portal

The MODULATION section of the ADVANCED PAGE is made up of two freely assignable Clickable Envelopes.


Adjusting Clickable Envelopes

Adjusting Nodes

Click to add nodes. Double click to remove nodes. Click and drag to move nodes. Click and drag lines between nodes to change curve.

Assigning Modulation

Assign Modulation by dragging and dropping colored Modulation indicators ( + ) onto a knob. Set Modulation Depth by clicking and dragging on the Modulation circle beside the assigned knob. Right-click a knob to reset to default, and to remove all modulation.

Editing Modulation

Right-click on a Modulation circle to select between Bipolar, Unipolar, or to Remove Modulation.  Modulation takes on the current knob position as the zero point of modulation.

Change the zero position for Modulation depth with shift + click, then drag up or down on the assigned Modulation circle.
