The Ableton link is connecting without a problem in a TouchDesigner itself.
But if I put the .tox inside the COMP Engine, the connection is not working. And on the node I receive the next message: Warning: There were errors in the component (/project1/engine1)
Ya impossible to debug without an example. I’d like to take a look as this is an interesting use case.
That said, TDAbleton is quite a complicated system and may be a lot to run/debug inside an engineCOMP. It’s worth considering running it in another full TD instance.
