I don’t know if this will be helpful, perhaps MC will chime in.
Somewhere in this monster thread I had similar issues with Cubase 12 and 13. I also use custom port names.
MC put up a variant in a response to me that is numbered:
var currentVersion=“1.12.28.0”
When I got 14 I grabbed the latest version that is in the OP of this thread for a ‘clean start’ and had the same problems you describe.
I rolled it back to 1.12.28.0 and deleted the mkII 61 User Settings file so Cubase would make a fresh one (luckily I had backed up the remote folder ‘just in case’). This fixed the issue, as no matter what I tried with the OP version I kept having to redo the mkII to get it working, or in some cases I’d end up with several copies of the script running.
It’s been working well since rolling back…
I’m not sure if I have the *.midiremote installer file anymore. I see a few in my download folder but I have no way of opening them to see what’s in there or I’d repost it here.
If one scrolls back through all these posts it’s likely to still be here on the forum.
I’m mainly making this post in case it might help M.C. track down what, if anything was done differently in that 1.12.28.0 version of the script.
Here’s a zip of the directory as it appears in my “%Documents%/Steinberg/Cubase/MIDI Remote/Driver Scripts/Local/Arturia” directory.
