Music and Sound Editing/Generation from MIDI or MML Possible?

[cannin]

Is it possible to convert MIDI or MML (Music Macro Language) for use with Pyxel? The MML format seems to be similar to what Pyxel uses; is this correct? Is there any automated method (or tips) for converting from MIDI sounds to Pyxel perhaps through MML? Below is my attempt to compare using a simple song. The notes in Pyxel do not seem distinct unless the "r" (rest) pauses are added.

Demo pyxel App (my manual attempt)

import pyxel

class TwinkleApp:
    def __init__(self):
        pyxel.init(200, 150, title="Twinkle Twinkle Little Star")

        # Define the full melody for the song
        pyxel.sounds[0].set(
            # Melody for the entire song
            (
                "c2rc2rg2rg2ra2ra2rg2r"  # Twinkle, twinkle, little star
                "f2rf2re2re2rd2rd2rc2r"  # How I wonder what you are
                "g2rg2rf2rf2re2re2rd2r"  # Up above the world so high
                "g2rg2rf2rf2re2re2rd2r"  # Like a diamond in the sky
                "c2rc2rg2rg2ra2ra2rg2r"  # Twinkle, twinkle, little star
                "f2rf2re2re2rd2rd2rc2r"  # How I wonder what you are
            ),
            "s",  # Square wave
            "4",  # Volume
            "n",  # No effects
            30,    # Speed
        )

        # Play the melody in loop
        pyxel.play(0, [0], loop=True)

        pyxel.run(self.update, self.draw)

    def update(self):
        if pyxel.btnp(pyxel.KEY_Q):  # Quit the app with Q key
            pyxel.quit()

    def draw(self):
        pyxel.cls(0)
        pyxel.text(20, 70, "Playing Twinkle Twinkle Little Star", 7)
        pyxel.text(20, 90, "Press Q to Quit", 7)

Pyxel's text music format is different from MML, but I'm planning to implement the MML feature in 2.2.3.
