Thanks everyone for such helpful replies. For some reason I thought this would be slightly more straightforward.
@dscheiba this is very helpful to know. Both the bridge and the P5JS side I’m trying to currently work out. I will take a closer look at the GitHub link you sent.
One thing I’m questioning, is if this is not being done regularly am I using the right graphics tool (P5JS)? If anyone reading this is sending OSC messages from Supercollider for the purpose of visualising in another software it would be great to hear about your experience and what software you are using to visualise. I like the idea of it all being open source, but I’m open to everything.
If it’s of help to anyone now or in the future Eli has a great video on OSC and Supercollider… https://www.youtube.com/watch?v=HzaS5kcAXiE&t=1282s
Also there is an interesting book about visualisation in Supercollider, but I don’t think that it covers OSC… Mapping and Visualization with SuperCollider | Business & Other | eBook
Thanks, Dom
