I'm using Kontakt on Windows 7.  The MIDI file think would be good, but
(not having that computer in front of me) I don't think that Kontakt
had the ability to open a MIDI file.

Now, I know that I could load the file into Reaper, and use Kontakt
as a plugin.  My problem is that I can't afford to mess with GUI menus
during my composition process.  I need to edit a python program in
Vi, then slap it out to python, hearing the music, then edit again.
The cycle has to be very quick in order to get anything done.

Loading Kontakt with a bunch of samples is very time consuming, so
it needs to keep running.  Now, if I could find a program that would
interpret the MIDI file and send events off to Kontakt either as a plugin
or standalone, then the MIDI file generation idea would be perfect.
