Native JavaScript/Python Extension SDK for Cubase 16 (AI, Claude Code)

[arkdzo]

Hi Steinberg Team and fellow Cubase users,

I wanted to start a discussion about a massive workflow revolution that is currently happening in the industry and respectfully request a major feature for the upcoming Cubase 16 Pro.

Recently, Ableton introduced a new Extensions SDK for Live. It is an open, Node.js-based environment that allows users to build custom scripts that directly interact with the DAW’s structure—reading and rewriting tracks, clips, MIDI data, and project timelines.

While Cubase has always been the king of MIDI editing, and tools like the Logical Editor are legendary, a modern, fully open API/SDK would take workflow customization to an entirely different level. But there is a much more urgent reason why this is critical right now: Artificial Intelligence.

Because Ableton’s new SDK is built on standard web technologies, it is incredibly easy for AI coding assistants like Claude Code, Cursor, or ChatGPT to write these extensions. A producer no longer needs a computer science degree to create a complex, custom workflow tool. You simply write a prompt describing what you want to achieve with your tracks or MIDI, and the AI generates a working tool for you in seconds.

AI is rapidly being integrated into absolutely everything, and creative workspaces are currently undergoing a paradigm shift. This is a massive wave that Steinberg must not miss. If Cubase 16 Pro introduced its own modern, open SDK (perhaps based on JavaScript or Python) with deep read/write access to project data, it would birth an explosive new ecosystem. Users could easily generate customized batch-processing tools, advanced generative MIDI plugins, and unique workflow accelerators just by talking to Claude Code.

By providing an API designed with AI-assisted coding in mind, you would democratize DAW customization and allow users to mold Cubase exactly to their specific needs. Please consider adding a native Extension SDK to keep Cubase at the absolute cutting edge of music technology.

Thank you for your time, and keep up the great work!

Hi,

Add the optional feature-request tag to your post, please.

We can already do this with the Steinberg Gemini API and Claude, and a little help from m.c. of the Forum, who’s the API king.
Here’s what I’ve accomplished in a month, and I don’t know how to code.

You just need a little patience and some ideas or instructions to give the AI, because you remain in charge of the project.

Hi, I’ve noticed you’ve created a similar thread to mine, since we’re on the same boat. It’d be great if you could support my thread by commenting and upvoting (you can see this in the left-hand corner at the beginning of the thread). I’ve done everything I mentioned in yours.
