There is already a existing script for the C4, but it only covers EQ (but on 8 channels at once).
Yes, i did get the C4 working with the Remote Control Editor, however i need third party software like Bome Midi Translator for it to get this working.
Yes, @Martin.Jirsak and me started a script for the midi remote and the C4, that can do much more. However that project is paused since 7 months ago.
Yes, it could definetely be possible, to have a cool working script in the future. It just needs someone, who is capable of writing Java Script and understands the API. Unfortunately, i am not able to do this, but would gladly help, if there is help needed understanding the C4 device itself.
