Hi,
I've received the showfile and backup, most of it is setup correctly.
The reason why it is not working, is that an OSC tag should always start with a slash (/) .
So in Editor, if I change the OSC tag from "1" to "/1", and I send an OSC message containing a float of 0.00 to the OSC tag "/1", the fader is set to 0%.
Also I noticed the "Forward" option is set for OSC in the CueCore2 settings page. I believe this is not necessary in your setup, and might cause issues. This will forward every message send to the CueCore2 back to the KioscTouch (more exactly, to every OSC target set on the settings page)
I will reply to your email with a few screenshots of what I changed to get it working.
Greetings,
Bootsy
