Getting key signature, time signature and different instruments from a midifile

[GardSveen]

Hi. I am wondering how i can get the key signature and time signature from a midifile. And i was also wondering how to get the different instruments and the notes belonging to them(for example getting the notes in the treble and bass staff from piano notation into 2 different arrays).

Hi,

First of all, there are no such things as treble and bass staff in a MIDI file. MIDI file contains track chunks. We can get of course Key Signature and Time Signature events (there can be multiple such events in a MIDI file) and then you can decide by yourself where treble staff and bass one.

Please give me a MIDI file you want to retrieve the info from and I'll be able to say more. And also please say where bass and treble staffs in the file.

Hi i figured it out after reading more about track chunks. Thanks for the help.

Sorry for a bad example. What i am having trouble with is taking a midi file made in for example Sibelius with multiple instruments(for example Piano and violin). And then getting the notes belonging to them. I have made a function that uses GetNotes() and returns an array with all the notes(see code), but i want to have different arrays for different instruments. Is this posible?

public Melanchall.DryWetMidi.Interaction.Note[] GetMidiNotesArray(){
var notes = midiFile.GetNotes();

    var array = new Melanchall.DryWetMidi.Interaction.Note[notes.Count];
    notes.CopyTo(array, 0);

    return array;

}
