Thanks!
Here is a workflow I just discovered, but it requires you to have a Mac running Isadora (or equivalent) on your network:
I found this piece of MAC-only software which will make the bridge between any OSC transmitting software (in this case Isadora) and ATEM switchers
https://www.buechele.cc/blog/2013/2/5/a ... -switchers This will let me control ATEM switchers easily.
Then I just need to set up a TCP connection from WD where custom script buttons will then trigger the corresponding ISADORA actors.
