As for USB Midi- with Linux it just works. You just need the snd-usb-audio module in your kernel (almost always autoloaded these days). Then it shows up as a standard ALSA midi device. I suggest using qjackctl (even if you aren't using jack) to manage these- it's really good and makes everything make much more sense. I never did manage to get Windows MIDI to work properly. From what I can gather their way of connecting things up is just silly. You won't have any latency issues if you use the USB midi, whereas you might if using ordinary midi connections.
