Detailed Description

Extended plug-in interface IEditController for key switches support: Vst::IKeyswitchController.

• [plug imp]
• [extends IEditController]
• [released: 3.5.0]
• [optional]

When a (instrument) plug-in supports such interface, the host could get from the plug-in the current set of used key switches (megatrig/articulation) for a given channel of a event bus and then automatically use them (like in Cubase 6) to create VST Expression Map (allowing to associated symbol to a given articulation / key switch).
