hey , just started with touch designer recently.
working on a project and can't seem to troubleshoot the problem. routing math1 to midiout1 IAC DRIVER BUS. I'm struggling to get output in the device mappings dialog window? anyone can help diagnose the problem ? I feel like the problem lays within the midiout dest tab.
Sorry if this has been asked before.
