• Channel Pressure
• Control Change
• Note On / Off
• Pitch Bend
• Polyphonic Key Pressure
• Program Change
• Non-Registered Parameter Number (NRPN) (used to send/receive 14-bit parameter and value)
• System Exclusive (SysEx)

See changelog for version history.

Example

// List all available MIDI API's
foreach (var api in MidiDeviceManager.Default.GetAvailableMidiApis())
    Console.WriteLine($"Available API: {api}");

// Listen to all available midi devices
void ControlChangeHandler(IMidiInputDevice sender, in ControlChangeMessage msg)
{   
    Console.WriteLine($"[{sender.Name}] ControlChange: Channel:{msg.Channel} Control:{msg.Control} Value:{msg.Value}");
} 

var devices = new List<IMidiInputDevice>();
try
{
    foreach (var inputDeviceInfo in MidiDeviceManager.Default.InputDevices)
    {
        Console.WriteLine($"Opening {inputDeviceInfo.Name}");

        var inputDevice = inputDeviceInfo.CreateDevice();
        devices.Add(inputDevice);
        
        inputDevice.ControlChange += ControlChangeHandler;
        inputDevice.Open();
    }

    Console.WriteLine("Press any key to stop...");
    Console.ReadKey();
    
}
finally
{
    foreach (var device in devices)
    {
        device.ControlChange -= ControlChangeHandler;
        device.Dispose();
    }
}

RtMidi Version

We are using a fork off rtmidi master branch with a few changes (you can see a diff here between our fork and official repository) to make it possible to build on the platforms we are interested in and with changes to better support .Net P/Invoke.

You can find our fork at micdah/rtmidi.
