Yes, I can never get two H9s to work with H9 Control. I sometimes can get one attached to H9 Control on my 2019 MacBook Pro via a Roland USB midi adapter. And sometimes one on Bluetooth but never both at the same time. With Bluetooth I always have to go to H9 Control and connect manually. It is weird that there is so little support for using H9 Control with such a sophisticated pedal. I have 3 of the big Strymon pedals all connected at the same time to their Nixie software via the Roland USB midi adapter and it works great.
