MidiExternalPlayer is a Prefab, available with the Pro version, able to play Midi music from Midi file but outside the Midi database defined with MPTK:

Play Midi from :

• a folder on your desktop or
• a web site or
• a byte array.

Some points:

• This Prefab is available with MPTK Pro.
• No line of script is necessary to use this Prefab (out of byte array, obviously). All the job can be done with the inspector.
• But an API exists for more sophisticated needs in your application. See an example with source code at the end of this page.

Inspector parameters

When running:

• Midi URL or file path type a file path or an URL, select from a folder, clear the content. Example of path:
  • Windows: file://C:/Users/Thierry/Desktop/Midi/WishYouWereHere.mid
  • Mac: file:///Users/thierry/Desktop/Nirvana.mid
  • Web: http://www.midiworld.com/midis/other/bach/bwv1060b.mid
  • Or use the browser icon (on left) to select a file from your desktop.

Others Foldout

The inspector inherits of all properties of the MidiFilePlayer inspector, see below for a detailed explanation of others properties .

• Foldout Midi Parameters See here

• Foldout Midi Info See here
• Synth Parameters See here

Integration of MidiExternalPlayer in your script

See TestMidiExternalPlayer.cs and events associated in the canvas gameobjects of TestExternalMidiPlay scene for the whole example.

using MidiPlayerTK;
...
// MPTK component able to play a Midi file from an external source.
// This PreFab must be present in your scene.
public MidiExternalPlayer midiExternalPlayer;...
...
// This method is fired from button (with predefined URI) 
// or input field in the screen.
public void Play(string uri)
{
    Debug.Log("Play from script:" + uri);
    midiExternalPlayer.MPTK_Stop();
    midiExternalPlayer.MPTK_MidiName = uri;
    midiExternalPlayer.MPTK_Play();
}
// Play a predefined Midi from the web
public void PlayStatic()
{
    midiExternalPlayer.MPTK_Stop();
    midiExternalPlayer.MPTK_MidiName = "http://www.midiworld.com/midis/other/bach/bwv1060b.mid";
    midiExternalPlayer.MPTK_Play();
}

public void PlayFromData(string filepath)
{
    // example with filepath = C:\Users\xxx\Midi\DreamOn.mid
    try
    {
        // try to load a byte array and play
        using (Stream fsMidi = new FileStream(filepath, FileMode.Open, FileAccess.Read))
        {
            byte[] data = new byte[fsMidi.Length];
            fsMidi.Read(data, 0, (int)fsMidi.Length);
            midiExternalPlayer.MPTK_Stop();
            midiExternalPlayer.MPTK_Play(data);
        }
    }
    catch (System.Exception ex)
    {
