Detailed Description

Wrapper MPE Support interface: Vst::IVst3WrapperMPESupport.

Implemented on wrappers that support MPE to Note Expression translation.

By default, MPE input processing is enabled, the masterChannel will be zero, the memberBeginChannel will be one and the memberEndChannel will be 14.

As MPE is a subset of the VST3 Note Expression feature, mapping from the three MPE expressions is handled via the INoteExpressionPhysicalUIMapping interface.
