I was trying to connect the H9s from the bluetooth preferences screen in OSX. If that's something you can do from within the Eventide desktop app I will try there instead.

Regarding screenshots, I can do that when I'm next in from of my music computer.

Yeah, please try that. You can connect to your H9 once you open H9 Control: "Manually select a device" -> "Connect via Bluetooth" -> choose an H9 and click "Browse"

After it connects, you can click "Devices" in the top menu bar and then click "Connect a device via Bluetooth" to connect to the second H9
