@sunep: thx for your reply. but i checked behringers pdf already, and the function for changing a scene is not documented.
and my secound problem is, that if i know the command, i couldn’t implement it in vvvv, because my vvvv and osc know-how is too low. in other words, i am a vvvv rookie.
I dont know that mixer, but a few things you could do:
ASK on THEIR forum for the OSC command to change a scene!!
Check if their are other Tools that do what you want to do, and than use a OSC sniffer to know the proper commands.
For your vvvv problem, check some OSC examples in the contibution, for other software, and see how they did it, resolume-avenue-3 for example.
