Field

Description

dllPath

Full path to the VST3 module (a .vst3 file), which implements the effect

filterName

Name of the VST3 effect. If the module has only a single effect (a quite common scenario), this parameter can be omitted.

parameters

An array of parameters, which define the settings of the effect.

"id" / "title": Either the numeric ID or the title of a parameter must be specified.
"normalizeValue": The normalized value of the parameter, which is always a floating point number between 0 and 1. This can be omitted, if a "stringValue" is specified.
"stringValue": A string representing the value of the parameter.
- If "normalizedValue" is specified, "stringValue" is ignored.
- Some parameters of a VST3 effect might not accept a string value.

An external helper tool is needed, to get IDs/names and possible values of all effect parameters!

Any effect parameters, which are not specified, keep their default values.
