That could be valid. Only 10 of the 25 workstations in the MIDI/audio/video lab have MIDI keyboards with built-in MIDI to USB interfaces, the other 15 MIDI keyboards are older models without USB connections. I want to keep them all cabled up the same. I want the students to see that MIDI and USB cables/data are actually different. If just using the USB connection with the MIDI keyboards builtin MIDI interface, then the students don't see that the MIDI cables and data are different to USB, and that the MIDI goes through a MIDI to USB interface before going into the computer, as the MIDI 'cables' and MIDI to USB interface are built into the keyboard. If it was my home setup, then yes, the USB cable would be enough, but in a teaching situtation in a lab of 25 workstations, I'd like to have them all the same and using MIDI cables to an external MIDI interface.
