    I can easily create rhythms and songs from a midi sequencer as: https://onlinesequencer.net/

    Also, I can create sound effects using musical notation and a multitude of instruments.
    And all this from a .dll plugin 68 KB with 128 instruments: http://grouplab.cpsc.ucalgary.ca/cookbook/index.php/VisualStudio/HowToPlayMIDIInstruments

    This plugin uses a static class MidiPlayer, and the static method Play to listen to songs and musical notes.

    This static class makes Unity remains frozen when you hear a song file .mid.

    I've been using System.Threading to create a unique thread for MidiPlayer.Play but I have not succeeded.

    Some help?

    Not to start from scratch. Here is the link of the Project:https://forum.unity3d.com/attachments/unitymidi-unitypackage.205244/?temp_hash=2eb13a5b59f9e4640f57dc1f59bbf6ff
