I have two sets of two MIDI keyboards on each of the two "L" shaped stands. Each cable connects to a multiport USB hub and then to a computer to create music. This simplifies cable labeling and identification. I put a numbered cable marker (from 1 to 4) on each keyboard as well as on the cables at the end of the USB hub. This simplifies and describes my connection of each keyboard to the hub and computer for easy instant identification and routing. These cables are long enough to get the job done without creating a "trip hazard"; and get the job done. They are cool!
