我可以更改mciSendString的输出midi设备吗

所以我终于在这个类上找到了一个帮助我的帖子

using System;
using System.Text;
using System.Runtime.InteropServices;
using System.IO;
namespace MidiProgram
{
/// <summary>
/// MCIPlayer is based off code by Slain.
/// Found here: http://www.sadeveloper.net/Articles_View.aspx?articleID=212
/// </summary>
public class MCIPlayer
{
    private static readonly string sAlias = "TeaTimerAudio";
    [DllImport("winmm.dll")]
    private static extern long mciSendString(string strCommand, StringBuilder strReturn, int iReturnLength, IntPtr hwndCallback);
    [DllImport("Winmm.dll")]
    private static extern long PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);
    public static void Play(string sFile)
    {
        _Open(sFile);
        _Play();
    }
    public static void Stop()
    {
        _Close();
    }
    private static void _Open(string sFileName)
    {
        if (_Status() != "")
            _Close();
        string sCommand = "open '"" + sFileName + "'" alias " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }
    private static void _Close()
    {
        string sCommand = "close " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }
    private static void _Play()
    {
        string sCommand = "play " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }
    private static string _Status()
    {
        StringBuilder sBuffer = new StringBuilder(128);
        mciSendString("status " + sAlias + " mode", sBuffer, sBuffer.Capacity, IntPtr.Zero);
        return sBuffer.ToString();
    }
}
}

然而，我似乎发现了一点问题，整个程序声音，但显然它输出到（微软gs波形表合成器）在这个类中，有没有一种方法可以改变midi的输出方式，或者它只是像MediaPlayer那样以这种形式播放，请告诉我，这是我项目的最后一步，只是一个简单的代码，我可以这么做，我可以用整数或其名称指定midi设备吗，我指的是midi设备的顺序！
