Hi there , if any body can help me please i have been using rig manager with usb to Kemper stage , and was working fine , now i have upgraded OS firmware to 10.1.1 and now rig manager has lost contact with stage suggesting i may be using hub or bad cable , but it was working well until OS upgrade . I'm using mac book pro running OS 10.14.6 has anyone a solution to this problem , I'm old and my eyes don't work as well as they used to so editing via the stage is very hard for me i have come to rely on rig manager . i have reverted back to firmware 9 and have communication again , so i know its not my cable ! Anyhow i hope your all well and enjoying your Kemper's as much as i am . Dave
