How do I add the midi format to player(gstplayer?) in kivy?

[Jungkyu]

Hello,

I try to make midi sound player in kivy

Kivy soundLoader can import the midi file and play

However, it dosen't control the play, e.g. sound.length, sound.get_pos function.

I opened the players in audio package and cannot find player to play .mid file

I attempt to add the 'mid' in gstplayer but it refused.

class SoundGstplayer(Sound):

    @staticmethod
    def extensions():
        return ('wav', 'ogg', 'mp3', 'm4a', 'flac', 'mp4')  <--- attempt to add 'mid'

    def __init__(self, **kwargs):
        self.player = None
        super(SoundGstplayer, self).__init__(**kwargs)

How do I make the midi control?

Do I change package?
