Maestro: A free tool to transform your MIDI

Hi everyone!

A month ago, I shared the first beta of my free M4L device, Maestro, and got some amazing feedback. I'm excited to share a big update based on that input.

For those who tried the first version, it's is now more steerable and gives you significantly more creative control.

Maestro is a tool I built because, as a producer myself, I wanted a way to quickly explore new variations on my existing MIDI ideas without ever feeling like I was losing control of the process.

What does it do?

Instead of manually editing notes in the piano roll, Maestro lets you transform your MIDI using high-level musical commands. It's designed for when you have a starting point—a melody, a chord progression—and want to see where else it can go. It’s all about making it easier to bring ideas to life without losing any of the joy of making music.

How it works:

You send a MIDI clip from Ableton to the tool, which opens in your web browser. Once there:

1. Build a Plan: A plan is a sequence of musical operations (like `harmonize`, `syncopate`, `add swing`) that you apply to your MIDI. You can target specific bars, beats, or even individual notes and describe the change in plain text. No advanced music theory required, just your ideas. You can also have the system build a plan for you and modify it before executing it.

2. Execute and Listen: Click "Execute Plan," and Maestro applies your changes. You can then sync the transformed MIDI right back into your Ableton track with a single click to see how it sounds.

3. Iterate Freely: The system saves checkpoints, so you can easily go back to a previous version and try a different creative path.

A Quick Note on the Tech

For full transparency, Maestro uses AI to work with MIDI. My design philosophy was to create a tool for transformation, not generation. I’m very against any AI that replaces creativity, and this is my attempt to see how new technology can empower artists instead. Maestro handles the low-level MIDI changes but still requires artists to define what they want changed. I’d love to know what you think of this approach.

I Need Your Feedback!

This is a free beta, and your input is incredibly valuable for shaping its future. If you have a moment to try it out, I'd love to know:

* Was the process intuitive for you?

* Did it help you come up with an idea you wouldn't have otherwise?

* What is the #1 feature you'd love to see added?

How to Try It:

Go to www.maestrobeta.com to download the device. It requires Ableton 11 or 12 with Max for Live.

Thanks for checking it out. All feedback is so, so appreciated.

Happy creating
