GetParameter function in Scripter MIDI plug-in in MainStage

The GetParameter() function retrieves information from parameters defined with var PluginParameters. Parameter variables can include type, minimum and maximum range values, and default values within the defined range, for example. Also see Create Scripter MIDI plug-in controls.

The GetParameter name argument must match the defined PluginParameters name value.
