private int _midiStream;
...
// create a MIDI input callback delegate
_midiProc = new MIDIINPROC(MyMidiInProc);
BassMidi.BASS_MIDI_InInit(0, _midiProc, IntPtr.Zero);
...
// create a MIDI stream to play the MIDI data
_midiStream = BassMidi.BASS_MIDI_StreamCreate(16, BASSFlag.BASS_DEFAULT, 44100);
...
private void MyMidiInProc(int device, double time, IntPtr buffer, int length, IntPtr user)
{
    // forward the data to the MIDI stream
    BassMidi.BASS_MIDI_StreamEvents(_midiStream, BASSMIDIEventMode.BASS_MIDI_EVENTS_NONE, 0, buffer, length);
}

Private _midiProc As MIDIINPROC
Private _midiStream As Integer
