There is a little coding window in Reaper, but it doesn't "vibe code." I am positive Reaper will never contain AI functions, knowing how Justin operates.

However, I did recently "vibe code" a function in Reaper via Grok. via JSFX (often just called "JS") / Jesusonic (or JesuSonic)

I told Grok what I needed, it gave me the code, I entered into Reaper, tested, asked for an improvement, tested, and was done.

Worked great.

It's NOT in any way "AI music" (which I would never do), it's AI helping with the backend of the tools.
