HELP !!! Notes in panel to midi file??

Hi at everybody! I m stuck in a very tiny question of sintax I have done an example to see the midi notes from a file into a panel. Ok!

But now just want to export the notes located in the panel to an archive.mid In a word to make the reverse function!

namespace panel_basic
{

	public partial class Form1 : Form

	{
		

		public Form1()

		{
			InitializeComponent();
		}

		private const int ALTURA_NOTA = 3;
		private const int ANCHO_NOTA = 6;

		private void Form1_Load(object sender, EventArgs e)
		{

			if (System.IO.File.Exists( "01.mid"))
			{
				Cargar_Notas( "01.mid");
			}
			else
			{
				MessageBox.Show("Not found 01.mid", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
			}

		}

		private object Cargar_Notas(string file)
		{

			NoScrollPanel1.Controls.Clear();

			MidiFile midiFile = MidiFile.Read(file);
			var notes = midiFile.GetNotes();

			foreach (var note in midiFile.GetNotes())
			{

				var x = (note.Time * ANCHO_NOTA ) + 127 ;
				var y = 480 - (note.NoteNumber) * ALTURA_NOTA ;
				var width = note.Length * ANCHO_NOTA;
				var height = ANCHO_NOTA;

				Panel rectangulo = new Panel();
				rectangulo.Location = new Point((int)(x / 10), y);
				rectangulo.Size = new Size((int)(width / 10), height);
				rectangulo.BackColor = Color.Cyan;			
				NoScrollPanel1. Controls.Add(rectangulo);

			}
			
			return null;
		}

	}

}

Yeah! Now IT runs good, but needs to replace the ppq to 960. I use your : TicksPerQuarterNoteTimeDivision in the write function. And the result its very good. Thanks a lot. I Will post the final result as a very aceptable semi-piano roll viewer and editor notes here in Github

Also length should be the second argument in the constructor, not the third one. And this also is specified in the documentation:

public Note(SevenBitNumber noteNumber, long length, long time)
