So I rolled “my own” midi remote script for the iCON QCon Pro X control surface. That is to say, I adapted the hard work by @bjoluc to work for the Pro X, supporting the second display and the master VU meter (more or less 
)
Full disclosure: A lot of work was done with Gemini-AI-support to make it all go a bit faster. I’m an okay-ish coder, but JAVA is the jungle I usually live in, not Typescript.
Should work in Cubase 12 and above. There’s some code in there that could be stripped out, but that would result in the script only working in C13 and above, so let’s keep it as it is for now.
If you have extenders, you can add them at the top of the javascript. Just make sure they are in the order they appear on your desk. I tested this with the main device + an extender. Fingers crossed it works with more than one extender.
Current apparent issues:
* Main stereo VU meter is not showing stereo levels (not sure this is even resolvable atm)
The javascript file and the source is here (look at RELEASES for the actual script):
But if you’re not confident about the placement of the js-file I have included midiremote files that you should be able to simply import below.
Just the main unit:
iCON_QCon Pro X.midiremote (57.7 KB)
Extender on the left side, main unit on the right
iCON_QCon Pro X_extender+main.midiremote (58.4 KB)
Main unit on the left side, extender on the right
iCON_QCon Pro X_main+extender.midiremote (58.4 KB)
Let me know if there are any issues OR things I missed OR if you have any good ideas for improvements or stuff that is missing. No promises.
