Detailed Description

Extended Plug-in interface IEditController for key switches support.

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).
