No.. There are about another 25 drivers and the MIDI stuff to convert. At a
rough guess it's about 3 or 4 man days of effort for an individual who has
some level of familiarity with the audio code. With all three of the
projects it's more a case of "many hands make light work".

FWIW, here's the task list I have been maintaining. It's a bit rough but it
does show some of the things that need doing:
