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).
