@wehrk Have you reviewed the OSC page in the Tidal user docs?
There is a section on Multiple Targets and messages.
I regularly use Tidal with Max, sometimes routing SuperCollider audio output to Max for processing with VST plugins, sometimes routing OSC messages so that patterns & parameters in Tidal route directly to Max for synthesis, and sometimes I use Tidal to control both SuperDirt and Max. I posted details on one project here: Troubleshooting custom OSC - #7 by HighHarmonics It contains a link to a GH repo I with the tidal and Max files.
