I work with OSC a lot mostly for communicating between apps and code, rather than external controllers.

I would like to share a script that I created during my research residency at ZKM earlier this year, useful for rewriting from standard OSC message syntax to Kyma widgets – directly in the Kyma signal flow.

This can be very handy when working with a large OSC protocol, that has many repeated messages, for example the Sonic Emotions Wave I wavefield synthesis system or Iannix gesture sequencer.  You can copy and paste a long list directly into the script.

Use this in a Script Sound and it will create widgets for you with the correct OSC formatting, contained in an array called ?IncomingOSCMessagesRewrittenForKyma 

You will then need to collect this array using a  SyntheticSpectrumFromArray or (if you are a NeverEngineLabs subscriber ) our ArrayToGlobal Controllers Class.

Good luck!
