Hello, Welcome to the Forums.
The best doc I’ve seen on patchwork implementation so far is this one.
I haven’t used Patchwork enough to speak intelligibly about it. But looking at the ‘Note Trigger Device’ API it seems that there are no functions that would make sense to subscribe to.
I see you’ve found the upcoming Patchwork AMA, let us know if you find out how to do this in the mean-time.
