Generic Controls

Purpose

The Generic Controls device is used to create a number of different controls in the project, including:

• knobs
• faders
• buttons
• meters.

When you drag a Generic Controls device over to the page, you can specify the type and range of values it will control. You can then open the Controls block that has been created and change the properties of the control inside to select the style: knob, button, meter etc.

For every actual/native control that is used to control the DSP algorithms, there is a generic control that can be used to mimic, as well as range-limit, the actual control. A good example is a level control inside a mixer. The normal range for a mixer input level is -100 to 0 dB. A generic level that has min/max values of -18 to 0 dB could be connected to the actual control, which is the control the end-user or external control systems uses. The input is then limited to the values set in the generic control.

Generic controls can be controlled using RATC from applications outside NWare. You can specify values for controls using the controlSet command and read control values using the controlGet command. For more information, see External Control in the External Control User Guide.

Tips:

• If you set the Number of controls value on the device properties to greater than 1, you can create multiple controls of the same type in one operation.
• The options available on the Style tab depend on the control style you select. For example, a meter has options for orientation and labels, whereas a text box has options for font size, background, and so on.
