ease of use,simplicity,final product,ability to change things on the fly-these are why digital is going to take over.
many times in studios,the drums are triggered anyways.
with that in mind what makes more sense?
tracking real drums is dead for the most part.
and i am a huge fan of drums.from a players standpoint,i will always stick with an acoustic set.
from an engineering standpoint,it doesn't prove itself beneficial to use real drums.
YMMV.
