As well as receiving and responding to OSC messages, the OSC Plugin for Ensemble can send OSC messages. OSC messages are specific to individual devices and software so you need to ensure that the information matches at both ends.
I’ve put together an example output block to control a virtual LED in TouchOSC. In a similar way to Push and Toggle buttons, you can place an LED element on a TouchOSC layout. These ‘light’ when a message is received, with the brightness related to the value sent.
You need to ensure that you change the ‘Server’ setting to match the ‘Local IP address’ on the receiving TouchOSC software.
