Knobs

It is easy to control Pro-C'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 the current value of the parameter.

All knobs support four 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.
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 precise adjustments.
Mouse 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 is the active window.)
Text entry mode
Double-click on a knob to enter the value exactly using the keyboard.

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.
To fine-tune a value when using vertical drag mode or the mouse wheel, hold down the Shift key while dragging or moving the mouse wheel.
Some controls are linked to each other so they can be adjusted together by holding down the Alt key (Windows) or Option key (OS X) while dragging one of the knobs. This applies to the Output and Dry Mix knobs and the two Side Chain Level knobs in Expert mode (both the inner knob and the outer rings).
In text entry mode, there are several handy shortcuts. With time values, you can type e.g. '10 ms' or '0.5 s'. With dB values, you can type e.g. '2x' to get +6 dB (the value that corresponds to two times louder). With all values, you can also type a percentage (e.g. '50%' will put a knob exactly in the middle position).
Pro Tools note: the RTAS plug-in uses 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).
