Maestro vs xLights for Tesla light shows
There are two main ways to make a custom Tesla light show: sequence it yourself in xLights, or generate it from a song with Maestro. Maestro is made by Molargik Software, the publisher of this site, so weigh this accordingly. This comparison tries to be fair, because each tool is the better choice for some people.
Both produce the same thing: a .fseq file and an audio file that you put in a LightShow folder on a USB drive. The car does not know or care which tool made them.
Checked against Tesla’s published light show guide on November 12, 2026.
xLights
xLights is free sequencing software, and Tesla publishes a project folder that sets it up for Tesla vehicles. It includes a 3D preview, example sequences, and a layout covering every light and closure on every supported car.
Strengths:
- Free, and it is the tool Tesla’s own instructions are written for.
- Total control. You place every effect on every channel, down to individual LEDs on the Cybertruck light bars.
- Large community. Tesla links to shows and communities, and plenty of general xLights tutorials exist.
Costs:
- It is manual. Tesla’s guide covers the Tesla-specific setup and then points you to online resources for the general sequencing workflow. Expect a learning curve.
- A good show takes time, because you build it effect by effect.
- You manage the details yourself: FSEQ version, frame interval, audio sample rate, and the closure command limits.
Maestro
Maestro is an app for iPhone, iPad, and Mac. You give it a song and it writes a complete show in seconds by analyzing the music on your device. It supports every Tesla model that supports light shows, and it is free to try, with a one-time unlock and no subscription or account.
Strengths:
- Fast. A finished show from any song, without learning a sequencer.
- It follows Tesla’s published rules for you, including 44.1 kHz audio, and it validates the sequence.
- On the Mac, Install to USB checks the drive and writes the correct folder layout, and Export for Multiple Cars builds a show for each car in a row.
- You can edit what it makes. The Mac version has a channel-level editor, and you can reroll a take you do not like.
Costs:
- Less control than a manual sequencer. Maestro makes the creative choices first, and you adjust afterward.
- It runs on Apple devices only.
- It is paid beyond the free trial. Check the App Store page for current terms.
Side by side
- Cost: xLights is free. Maestro is free to try, with a one-time unlock.
- Time to a first show: Maestro takes seconds from a song. xLights takes as long as you spend sequencing.
- Control: xLights gives you every channel. Maestro gives you a finished show you can edit.
- Platforms: Maestro runs on iPhone, iPad, and Mac. For xLights, see xlights.org.
- Output: both make a .fseq and audio pair for the LightShow folder.
- Multi-car: xLights needs a separate file per car, made by hand. Maestro’s Mac export builds one per car.
Who should use which
Use xLights if you enjoy detailed sequencing, want to design every moment yourself, or already know it. It costs nothing but time, and the control is unmatched.
Use Maestro if you want a good show from a song without learning a sequencer, you have several songs to do before the holidays, or you want to light up a row of cars.
Use both if you like. Because the output files are the same kind, nothing stops you from generating a show with Maestro and comparing it with one you built by hand. Start with the overview guide for the full process, and the USB drive guide for the finish.
