I’m fairly sure that will not work because something-something USB Host vs something-something USB Device.
Pyramid needs a host to operate in this manner.
I think there are some class compliant MIDI Interfaces that may offer USB Hosting duties - I’d swear someone is using a something-something Mio for that.
In my rig I’m using a BomeBox for this duty. I wonder if the Blokas MIDIHub can accomplish this.
Of course, I’m probably wrong - in which case: apologies.
In good time someone smarter might chime in.
