sf2.export_midi_file fails about sf2_loader HOT 5 CLOSED

I see what is causing this issue here. Let me clarify the parameters of the function export_midi_file, the first parameter current_chord is the name of the midi file you want to export as audio files using loaded soundfont files, and the name parameter is the name of the exported audio file. Here your first parameter should be rf"{defaultPath}\generated_music.mid" instead of piece, and if the variable piece is the name of the exported audio file you want, you can set name=piece, but actually piece is a defined class in musicpy, so it is better to use another variable name to avoid naming conflicts.
Or if you actually want to export a piece instance to a midi file, just simply use musicpy's write function, like this:

write(piece1, name=rf"{defaultPath}\generated_music.mid")

from sf2_loader.

Does this mean I first have to generate an audio file, using export_piece and then I can use export_midi_file ?

The variable piece here is the output of calling piece from ``musicpy```, I can share a bit`more of my code:

 if(musicalParsing == "random"):
       # this is a musicpy chord object
        musicalOutput = lmusic_parser.random_parsing(output)
        piece = sf.mp.piece(
            [musicalOutput], [sf2.current_preset_num], random.randint(40, 220), [0], channels=[1]
        )

    now = datetime.datetime.now()
    now = now.strftime('%Y_%m_%d_%H_%M_%S')
    sf2.export_midi_file(
      piece, name=rf"{defaultPath}\generated_music_{now}.mid")

I will rename the variable, thanks for the tip

No, you can use musicpy's write function, which can directly output any musicpy data structures to a midi file.
The export_midi_file function of sf2_loader is to read a midi file, and render it to an audio file using loaded soundfont files, and then export the audio file. The write function of musicpy is to convert a musicpy data structure (such as note, chord, track, piece) to a midi file.

Thank you for the clarification! Feel free to close the issue.
