Example:

<werckmeister-workspace id="workspace"></werckmeister-workspace>

<werckmeister-editor
  id="ed1"
  wm-filename="main.sheet"
  wm-style="height: 700px;"
>
using "chords/default.chords";

tempo: 140;

instrumentDef:lead _onDevice=MyDevice _ch=0 _pc=0;
instrumentDef:rhythm _onDevice=MyDevice _ch=1 _pc=0;
instrumentDef:bass _onDevice=MyDevice _ch=2 _pc=0;

-- melody track
[
instrument: lead;
{
    \p
    r4 e f# g | c'1~ | c'4 d e f# | b2 b2~ |
}
]
</werckmeister-editor>

<a href id="download">Download MIDI</a>

⚙️ Step 3: Register the Editor in JavaScript

Link your editor to the workspace using JavaScript:

const workspace = document.getElementById('workspace');
workspace.registerEditor(document.getElementById('ed1'));

You can also hook into events:

workspace.onCompiled = (doc) => console.log("Compiled successfully:", doc);
