MIDI Trigger is a simple program designed to demonstrate how a MIDI input device can be used to trigger events in a game or an application.   MIDI Trigger was inspired by the scene in the Dark Knight Rises where piano keys were used to open the Batcave. Please see the Documentation section for information on how to use it. The project has been kept simple in order to show the main concept of using MIDI input and output with NAudio, so that it can be easily added to your own projects.  This project requires NAudio and a MIDI input device, such as a USB keyboard.
