Switch TOP by CHOPS

Hi
I have OSC channels from controller that work like radio button. If one is ON the others are switched OF. I need to transform them somehow that they become one channel (selecting the active channel) with specific number so I can use it to switch scenes in the Switch CHOP by changing the index.
Thank you so much !!!

You can use the Fan CHOP set to Fan In to turn many channels into one.

Thanks a lot!! Yeah I exactly figure out the solution with fan chop afterwards.
