Question

I am using MacBook Pro with the usb-c I have the adapter. When I connect the audiobox iTwo, there is power to it, however when I am attempting to connect the PS49 to the audiobox to use it as a midi control, there is no power at all to the keyboard. When I plug the keyboard directly into the computer, there is power, but I want to use it as a midi controller. PLEASE HELP.

Answer 1

You will need to connect the PS49 to your computer using USB, the AudioBox will not power the PS49.  The AudioBox will transmit MIDI using MIDI cables into your host DAW, I hope that clears things up for you.

You may also consider using a powered USB hub to connect all your devices.
