HI ianoreo,
I have looked into this a little bit and unfortunately this feature is still in experimental state and has no docs or tutorials at this time. I see that in another of your posts you mention that you have the ability to create your project using portmidi library and C++. I know that this is not your preferred method, but it may be your only option at this point. I am including a link to the trello roadmap page in case you don’t already have it.
This will allow you to vote on which features you think we should concentrate on going forward. I will make sure to keep an eye on this particular feature and I will let you know when changes are being made.
Thanks for your patience,
