For those that own a HSS3jb http://bleeplabs.com/hss3jb-user-guide/ here's a patch to let you control it from PD. Port number is set to default 1.

I haven't yet figured out how to add a toggle to control which mode it is in. I think it is expecting a button to be held down and [key] keeps sending a signal when a key is pressed, so it doesn't work properly.
