Knobs and switches
It is easy to control Volcano's parameters with the large round knobs and switches. They will light up when you move the mouse cursor around to indicate that you can adjust them. The moment you move the mouse cursor over a knob, a parameter value display will pop up, which shows the name and current value of the parameter.

All knobs support three ways of control:
- Vertical mode
Click on the center area of a knob and drag up or down to rotate it. The knob
reacts to the speed with which you are dragging, so if you move the mouse
slowly, you make precise adjustments. Hold down the Shift key while
dragging to force fine-tuning.
- Rotate mode
Grab the arrow of the knob and drag it around. By moving the mouse cursor
further away from the knob while dragging it, you can make very precise adjustments.
- Scroll-wheel mode
Perhaps the easiest way to make adjustments is by using the mouse wheel when
you you hover over a knob. This mode works for all the knobs and panning rings.
(On Windows, you might need to click in the plug-in interface first to make
sure it has the keyboard focus.)
Tips
- To reset a knob to its default position, hold down the Ctrl key (Windows)
or Command key (OS X) and click the knob once.
- When adjusting the filter frequency, pan, peak or delay knobs, you can hold down the Alt key while dragging to adjust all linked filters in parallel. See also Filters and Filter parameters.
- Pro Tools note: the RTAS version of Volcano 2 implements the default Pro
Tools keyboard shortcuts for fine tune (Ctrl+drag on Windows, Command+drag on
OS X), reset to default (Alt+click) and linked operation (Shift+drag).
