My set up is very simple. I using a the smallest phone power bank i could find and I use velcro pads to on the bottom of it to fix it on the top of the Ewi USB. Then I have the WIDI Uhost connected to the power bank, that send the current to power the WIDI Uhost. So the Uhost has two USB C ports, one is marked to USB power and the other is marked USB Host/Device. From the USB host/Device port I connect that to the EWI usb port. Both of my cable are 6inch USB cables. The other piece of gear is the CME WIDI BUD Pro. The USB Host need will communicate with the WIDI bud pro. The WIDI BUD Pro is connected to a USB port on my mac or PC. Remember this is midi over Blue tooth. The blue tooth on the mac wont see the just the Uhost, its the midi information from the EWi we want to get to play the sample in Kontact. This is my set up. However I also have The WIDI Master this is also made by CME. If I want to send midi to a Synt then I will use the WIDI Master. My configuration on the EWI USB will remain the same, the only difference is that instead of my midi going to the my WIDI BUD pro it will go to my WIDI Master which would be connected to my Synt. 5 pin Midi in and Midi out port on my synt. Hope this helps.

Yes you do.
