In this tutorial you will install the Live Set Viewer device in Ableton Live, open the interactive graph in your browser, and see your session’s tracks and devices visualized as a node graph. By the end, you will have made changes in Ableton and watched them appear in the viewer in real time.

What you will need

  • Ableton Live 11 or 12 (any edition that includes Max for Live)
  • A modern web browser (Chrome, Firefox, Safari, or Edge)
  • About 5 minutes

Step 1: Install the device

The Live Set Viewer device is a small Max for Live instrument that reads your session’s structure and serves it to your browser.

  1. Download the Live Set Viewer device from the download page (pick your price or download for free).
  2. Unzip the download. Inside you will find a file called Live Set Viewer.amxd.
  3. Open Ableton Live and create a new Live Set (or open an existing one with a few tracks and devices already in place — that will make the visualization more interesting).
  4. Drag Live Set Viewer.amxd onto any track.

Step 2: Verify the device is running

Open the Max Console to confirm everything started correctly. You can find it under Window > Max Console in the Max editor (double-click the device title bar to open the editor first).

You should see messages like:

lom-handler-v8.js: script loaded
Live Set Viewer server listening on http://localhost:19741

The first message means the device successfully loaded the script that reads the Live Object Model. The second means it has finished walking your session’s structure and the web server is ready.

If you do not see these messages, try removing the device and dragging it onto the track again.

Step 3: Open the viewer

Open your web browser and navigate to:

http://localhost:19741

You should see a dark canvas with your session’s tracks laid out as colored rectangular nodes. Each track shows its name in a header bar colored to match the track’s color in Ableton. Inside each track, you will see smaller nodes representing the devices on that track, connected by edges that show the signal flow from one device to the next.

The viewer includes a few navigation aids:

  • Zoom controls in the bottom-left corner (or use your scroll wheel)
  • A minimap in the bottom-right corner showing the full graph at a glance
  • A filter panel on the left side for narrowing down what you see

Take a moment to pan and zoom around the graph. If your session has return tracks, you will see them grouped below the regular tracks, with dashed animated lines showing send routing. The master track appears at the bottom.

Step 4: Make a change in Ableton

Now for the part that makes this tool come alive. Go back to Ableton Live and make a visible change:

  1. Create a new MIDI track (Ctrl/Cmd + Shift + T).

Switch back to your browser. The new track should appear in the graph within a moment — no need to refresh the page. The viewer stays connected to the device over a WebSocket and receives updates as they happen.

Step 5: Make more changes

Try a few more things and watch the viewer respond:

  1. Rename a track — double-click a track name in Ableton, type a new name, and press Enter. The track node’s header in the viewer updates to match.
  2. Add a device — drop an instrument or effect onto a track. A new device node appears inside that track in the graph.
  3. Mute or solo a track — click the mute or solo button on a track. The track node in the viewer shows a small M (red) or S (yellow) indicator in its header.

Each change streams from Ableton to the viewer in real time. You never need to reload the page.

What you accomplished

  • Installed the Live Set Viewer device in Ableton Live
  • Verified the device loaded and started the local web server
  • Opened the interactive graph visualization in your browser
  • Saw your session’s tracks, devices, and signal flow rendered as a node graph
  • Made changes in Ableton and watched them appear live in the viewer
