Glad to see this on here. I've been using an iPad as the "brain" in my music setup and found this project not long ago. I've since opened PRs for a couple of Line 6 pedals I've got. I've also got a Novation Launch Control XL 3, for which Ben (the creator) has made an editor available to make targeting specific devices much easier. I've had a few email correspondence with him regarding the idea of open-sourcing that editor and he's a super nice dude.
Thanks again, Ben! (if you're reading this)
