About MIDI

The Microsoft Win32 application programming interface (API) provides the following methods for applications to work with MIDI data:

The Media Control Interface (MCI). Although the simplest way to play a MIDI file is to use the MCIWnd window class, you can also use MCI commands to create a customized interface to a MIDI device. For more information about the MCIWnd window class, see MCIWnd Window Class. For more information about MCI, see MCI, or Media Control Interface (MCI).
Stream buffers. This format allows an application to manipulate buffers of time-stamped MIDI data for playback. Stream buffers are useful to applications that require more precise control over output than MCI offers.
MIDI services. Applications that need the most precise control of MIDI data typically use these low-level services.

This overview discusses each of these methods and provides an overview of the the MIDI Mapper.
