I have mine connected to a usb hub on my laptop @KidYoshi, with Ableton forwarding the midi to the Pyramid. This suits my particular setup.
If you want to go directly to the Pyramid you’d need something like the KMI MIDI Expander or any other usb midi host device (e.g. you can even DIY with an Arduino).
You can’t go directly via a usb hub as the Pyramid isn’t a usb host device.
