json-midi-encoder

This module encodes a JSON representation of MIDI data into a binary MIDI file.


By using this module it is possible to encode a JSON representation of a MIDI file into its binary
counterpart. That JSON representation can either be created from scratch or produced by parsing an
existing file with the midi-json-parser.

Usage

This module is distributed as package on npm. It
can be installed by running the following command:

``shell
npm install json-midi-encoder
`

The only exported function is called encode(). It expects to receive a JSON representation as its
only parameter. It returns a Promise which hopefully resolves with an ArrayBuffer containing the
binary MIDI file. Here is a little example.

`js
import { encode } from 'json-midi-encoder';

const json = {
division: 480,
format: 1,
tracks: [
[
{
delta: 0,
trackName: 'example'
},
// ... there are probably more events ...
{
delta: 0,
endOfTrack: true
}
]
// ... maybe there are more tracks ...
]
};

encode(json).then((midiFile) => {
// midiFile is an ArrayBuffer containing the binary data.
});
``

To see what kind of events this module can handle, you may want to have a look at the
JSON files used
to test this module. There is also a
TypeScript interface
which describes the JSON representation.
