Not sure where you are seeing a hub ? Most sound generating boxes with USB can operate in either mode so you can plug a keyboard straight in, no hub, PC or anything just as you would with DIN.</div>

<div dir="auto">If USB wasn’t a hub-based protocol with a built-in cost of adoption.
<div>The actual wiring for USB is just fine and getting better all the time. What’s wrong for MIDI is this 90s-era idea of a “peripheral” Zip drive that is powered by your gateway 2000 laptop. All that brilliant design thinking ruined USB for MIDI because a
hub is nothing but a toll gate we already paid for and nobody wants. Does anyone really want a hub at all?<br>
