2.callback
public enum OpenFlag:uint

3.打开设备返回值
public enum OpenMsg:uint

}
#endregion
4.midi帮助类
public class MIDIHelper
{
#region API
[DllImport("winmm.dll")]
static extern uint midiOutOpen(out IntPtr lphMidiOut, uint uDeviceID, IntPtr dwCallback, IntPtr dwInstance, uint dwFlags);//打开数字乐器接口输出

static extern uint midiOutClose(IntPtr hMidiOut);//关闭数字乐器接口输出
[DllImport("winmm.dll")]
static extern uint midiOutShortMsg(IntPtr hMidiOut, uint dwMsg);//发送数字乐器接口消息
#endregion
5.定义变量
#region 自定义变量
bool isOpen = false;
IntPtr DeviceHandle = IntPtr.Zero;
public bool Opend => isOpen;
#endregion
#region 方法
6.打开设备。
public void Open()
{
IntPtr device;//此处后续要用
uint hand = midiOutOpen(out device, 0, IntPtr.Zero, IntPtr.Zero, 0);
isOpen = hand == 0;
DeviceHandle = device;
}
///

public uint Play(uint msg,int time)//播放，尝试了很多写法，发现msg * 256 + 0x00403B90;基本正常，百度百科的方法声音沙哑（msg*256+144+volume*655536+channel）

Console.WriteLine(data);
uint ms = midiOutShortMsg(DeviceHandle,data);
System.Threading.Thread.Sleep(time);

}
else

}
public uint ChangeInstruments(MusicNo musicNo)//改变乐器

public void Close()//关闭设备
