Json to midi

[bbonczek]

Hi, I was searching in your documentation and tests, however I could not find feature I am interested in.

Is it currently possible to generate midi file from json, that was created via MidiConvert?

My use-case is :

1. translating regualar midi file into JSON via MidiConvert,
2. tweaking json in some text editor,
3. translating it back to midi

Did you look at .encode()? Based on both the README and the unit tests, it looks like that does what you want it to do.

It is almost, what I am looking for, but not exactly. encode() method allows me to transform MidiConvert object (that is created for example by using MidiConvert.create()) into midi file that can be started in media player.

What I am missing, is feature, that would allow me to transform json into MidiConvert object (deserialize it in other words).

Ahhh. I don't see a fromJSON(), but I bet you could open a PR for one.

Or, if something quick and dirty is more your style, maybe something like this?

const midi = new Midi()
const encoded = midi.encode.apply(myJSON);
midi.decode(encoded)

It would roundtrip through the encoder, which is a bit wasteful, but it would get you the object you wanted. Alternatively, I'd copy decode, name it static fromJSON, and modify it to parse a JSON object rather than a string.

I'll try with pull request :)

This can close now.

How do i use fromJSON() fx to get the midi file i mean how to get the midi file.
Say for example i put the json as input and call fromjson(myjson) then where is the midi file actually?
