Wwise SDK

Executes a number of MIDI Events on all nodes that are referenced in the specified Event in an Action of type Play. Each MIDI event will be posted in AkMIDIPost::uOffset samples from the start of the current frame. The duration of a sample can be determined from the sound engine's audio settings, via a call to AK::IAkGlobalPluginContext::GetAudioSettings.

Remarks

This function executes the MIDI Events without going through the message queue. In order to do so it acquires the global Wwise sound engine lock. It should therefore only be called from one of the global engine hooks (see AK::IAkGlobalPluginContext::RegisterGlobalCallback). Use AK::IAkGlobalPluginContext::GetIDFromString() if you use event names (strings).
