json cli [music scrolll + parts] export into audio [mp3, wav]

[aha917]

Your idea

When working with a set / a compilation of music scrolls at some point I want to:

• export the music scores,
• as well as their parts,
• in a self-defined structure
  using a cli batch mode / .json file.

As of the current version 4.6.5 of MuseScore, these the cli .json export is rather limited.

Problem to be solved

Currently: pdf, mxl, and mid exports work fine. But not .mp3, or .wav.

Here's an example of a .json structure:

[
    {
        "in": "myScore1.mscz",
        "out": [
            "./pdfs/myScore1.pdf",
            "./mxls/myScore1.mxl",
            "./audio/myScore1.mid",
            "./audio/myScore1.mp3",
            ["./pdfs/parts/myScore1 (", " part).pdf"]
        ]
    },
    {
        "in": "myScore2.mscz",
        "out": [
            "./pdfs/myScore2.pdf",
            "./mxls/myScore2.mxl",
           "./audio/myScore2.mp3",
            ["./pdfs/parts/myScore2 (", " part).pdf"]
        ]
    }
]

Another, thing that is missing in the .json cli is, to export the audio parts as well. So sth like:

[
    {
        "in": "myScore1.mscz",
        "out": [
            "./pdfs/myScore1.pdf",
            "./mxls/myScore1.mxl",
            "./audio/myScore1.mid",
            "./audio/myScore1.mp3",
            ["./pdfs/parts/myScore1 (", " part).mp3"]
        ]
    },
    {
        "in": "myScore2.mscz",
        "out": [
            "./pdfs/myScore2.pdf",
            "./mxls/myScore2.mxl",
           "./audio/myScore2.mp3",
            ["./pdfs/parts/myScore1 (", " part).mp3"]
        ]
    }
]

And finally, I would be great if one could simplify the syntax of the parts in the json:
["./pdfs/parts/myScore7 (", " part).pdf"]

Ideally this could simply look for example like:
"./pdfs/parts/myScore7 ($PART).pdf"
