(sorry for spamming this thread)I know the Source Audio guys are busy with about a billion things, but now that this problem has been replicated, maybe they can take a look at fixing the Hub firmware...
Problem went away. I've rearranged my pedalboard so that the HUB is now on midi channel 1 - reloaded the hub via USB with my saved patches and it seems to behave as it should. Been testing with sending it some midi PC's, CC's and other stuff and it seems to be working, software and all.
Now off to making patches and more importantly: music.
