Hi Thomas, and welcome to the forums.
I have no experience with the Sennheiser EM6000, can you tell me where to find info about its OSC capabilities and configuration?
To send OSC messages from the IoCore2 to a target, you will have to enter the IP address and port on the settings page of the IoCore2. This is on the web interface, you can reach it by pressing "Browse" in vManager while having the IoCore2 selected.
When that is setup, you can go to the ShowControl page to actually send the OSC messages. You will need to add an action list source first, which will be what triggers the message. In the action list you can then add an action. Edit the action you added, and setup the trigger values. You can then add the "OSC" task to the action, which will determine the properties of the OSC message to be sent.
When sending OSC from the Sennheiser to the IoCore2, you will need to make sure that the Senhheiser sends to the IP and port of the IoCore2.
After verifying that the IoCore2 receives the OSC messages using the monitor page, you can add the action list source "OSC" for receiving the OSC messages. This is also done on the ShowControl page.
Greetings,
Bootsy
