Create charts for Trombone Champ from midis, to be used with TrombLoader

• Midi Channel 1 is used for actual notes, while Channel 2 is used for multiple slide notes.
• A sequence of Channel 2 notes must end with a Channel 1 note. Also, please quantize your charts, the game hates unquantized notes.
• It's strongly advised to make your own MIDI files. Trying to import ones directly from the internet will probably result in a crash or a bunch of bad notes in your chart.

4. After you complete that, you'll be prompted to export your finished chart. This is the song.tmb file (use that filename as-is) that you will place in your custom chart folder.
5. To use your .tmb file for a custom chart, create a new folder in the CustomSongs directory created by the TrombLoader plugin using the following structure:

[your-song-name] # this is your folder that contains your custom chart materials
│   bg.png # your background image for the song
│   song.tmb # your .tmb file generated by Midi2TromboneChamp
│   song.ogg # your .ogg music file that will play during your song

Midi2TromboneChamp exports JSON in the following format that represents a chart:
