Not sure I understand the functionality of this... Would this hub allow me to use one of those compact desktop MIDI controllers (which typically have only USB MIDI) with a hardware module like the Roland BK-7m? Does it introduce any latency compared to using a MIDI controller with a traditional DIN connector?

Finally, does it have enough ports to combine multiple controllers like a pad and a KB at the same time??

Sorry for all the questions, thanks! -Ted
