## Message Streamer
2
3
The Message Streamer publishes values over [ZeroMQ](https://zeromq.org/) to Pointreceiver clients, such as the CHOP in the [[TouchDesigner|Integrations/TouchDesigner]] integration. It is enabled by default.

Clients subscribe to the paths they're interested in. The last value of each path is retained, so a newly subscribed client receives the current value straight away instead of waiting for the next change.
