Introduction

Wrapper MPE Support interface: Vst:: IVst3WrapperMPESupport.

• [host imp]
• [passed as 'context' to Steinberg:: IPluginBase::initialize()]
• [released: 3.6.12]
• [optional]

Implemented on wrappers that support MPE (MIDI Polyphonic Expression) to Note Expression translation.

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

ⓘ Note
As MPE is a subset of the VST 3 Note Expression feature, mapping from the three MPE expressions is handled via the Vst:: INoteExpressionPhysicalUIMapping interface.
