使用NAudio库调用midiInOpen的内存分配错误

Question

我正在尝试编写一个程序来检测一个人从电子鼓组的midi输出中击中鼓的次数。我正在使用NAudio来处理这个问题。当我尝试选择midi输入时，我被告知存在“调用midiInOpen”的“内存分配错误”，我已经环顾四周，似乎无法找到任何可以解释我的问题的资源。 我的midi设备肯定被认可，目前我正在使用Yamaha piaggero NP-11键盘进行midi输入。

实际错误在第25行，我正在添加设备：

midiIn = new MidiIn(0);

这是我正在使用的代码：

class Program
{
    public MidiIn midiIn;

    static void Main(string[] args)
    {
        Program program = new Program();
        program.MainRun();
    }

    void MainRun()
    {
        Console.WriteLine(GetMidiInDevices()[0]); // This is just to check that a midi device is actually plugged in.

        midiIn = new MidiIn(0); // <-- THIS IS WHERE I GET THE ERROR 
        midiIn.MessageReceived += new EventHandler<MidiInMessageEventArgs>(midiIn_MessageReceived);
    }

    public string[] GetMidiInDevices()
    {
        string[] returnDevices = new string[MidiIn.NumberOfDevices];

        for (int device = 0; device < returnDevices.Length; device++)
            returnDevices[device] = MidiIn.DeviceInfo(device).ProductName;

        return returnDevices;
    }

    public void midiIn_MessageReceived(object sender, MidiInMessageEventArgs e)
    {
        if (e.MidiEvent != null && e.MidiEvent.CommandCode == MidiCommandCode.AutoSensing)
            return;

        if (e.MidiEvent.CommandCode == MidiCommandCode.NoteOn)
        {
            // As the Command Code is a NoteOn then we need 
            // to cast the MidiEvent to the NoteOnEvent  
            NoteOnEvent ne;
            ne = (NoteOnEvent)e.MidiEvent;
        }
        Console.WriteLine("Got input!");
    }
}
