Here's some code from http://www.geocities.com/foetsch:

MCI_OPEN_PARMS OpenParams;
ZeroMemory(&OpenParams, sizeof(OpenParams));
OpenParams.lpstrDeviceType = "sequencer";
OpenParams.lpstrElementName = "some.mid";

// Send MCI_OPEN
mciSendCommand(0, // We're retrieving this!
MCI_OPEN,
// Don't forget to set the appropriate flags!
// The flags will tell MCI which elements of OpenParams
// you set:
MCI_OPEN_TYPE | // because you set DeviceType
MCI_OPEN_ELEMENT, // because you set lpstrElementName
(DWORD)&OpenParams);

// start playback
mciSendCommand(OpenParams.wDeviceID, MCI_PLAY, 0, NULL);

// ...
// stop playback
mciSendCommand(OpenParams.wDeviceID, MCI_STOP, 0, NULL);

// close the device
mciSendCommand(OpenParams.wDeviceID, MCI_CLOSE, 0, NULL);


See the SDK docs for details about the mciSendCommand function and the MCI_
commands.

O, Plus 1 example(of Yoto Yotov ):
....
I have however an alternative which may be more suitable for you. The
mciSendString API function provides a quick and easy way to play all
sorts of multimedia files. Instead of using the memory-consuming and
sometimes unreliable MediaPlayer, you could simply send a few string
commands. For example:

1. Insert in your unit file:

#include <mmsystem.h>

2. Add a Button. Edit its OnClick event:

void __fastcall TForm1::MidButtonClick(TObject *Sender)
{
mciSendString("close MIDI", NULL, 0, 0);
mciSendString("open c:\\night.mid type sequencer " 
"alias MIDI", NULL, 0, 0);
mciSendString("play MIDI", NULL, 0, 0);
}

3. Edit the OnClose event of your form:

void __fastcall TForm1::FormClose(TObject *Sender, TCloseAction &Action)
{
mciSendString("close MIDI", NULL, 0, 0);
}
