Meter Control

Overview

Meter Control

Discussion

A Meter Inspector Control displays the value of a module variable over a range using linear or dB mapping. The range can be set using the max and min properties.

The mapping property can be used to map module variable to meter value directly (linear), or by converting with db20 or undb20 functions.

The modVar property must be set to point to a module variable. See the ParamSet module for more detail on modVar formatting.
