These devices use different firmwares and drivers, and as far as I know,
work flawlessly in Linux.  This appears to be a problem with the Windows
MIDI framework.  (Apparently, it behaves like the ALSA sequencer, i.e.,
drops data when its internal buffer overflows; there is no blocking API
like snd_rawmidi_*.)

Such a customization would be possible.  But it's unlikely that I will
find time in the near future.
