I have to admit I never tested two MIDI devices at the same time as I don't have many devices with multiple USB slots and I didn't think of trying to use the HP Slate 21 for that. I'll give it a shot with a couple of my class-compliant devices to see if I experience the same problems you described with the Superpowered library.
Thanks,
Mike
