3.打开设备返回值

4.midi帮助类

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()
{

uint hand = midiOutOpen(out device, 0, IntPtr.Zero, IntPtr.Zero, 0);
isOpen = hand == 0;
DeviceHandle = device;
}

else

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